Last year, Switched On discussed the KeySpan TuneView and the DLO HomeDock Remote, two products that allowed remote control of an iPod using small screens on a remote. One of the limitations of those products was that they each required their own docks instead of working with any of the scores of iPod docks already on the market. At CES 2008, though, a company showed a product that not only allows you to use your iPod -- and many other devices -- as a wireless remote with the iPod dock you may already have. Even more unusually, the company that sells it is not one well associated with these speaker docks, such as Altec Lansing, Bose or Logitech, but rather It is iSkin, a company that made its name selling silicone cases for iPods.

iSkin's music product line is called Cerulean, the most flexible configuration of which is the $129 TX+RX (transmitter / receiver). The transmitter, like those bundled with iPod wireless headphones for years, allows you to use your iPod as a remote, sending music to any Bluetooth stereo speaker. But not only does Cerulean free the iPod from the dock, it frees the dock from the iPod.

Plugging the Cerulean Bluetooth receiver into practically any iPod dock opens a door for many Bluetooth stereo music sources -- such as MacBooks and notebook PCs, digital music players from Sony and Samsung, and many cell phones. When used with a subscription service such as Rhapsody, the Cerulean lets you create playlists from thousands of songs or listen to YouTube music videos on your notebook with better audio quality, but there's even one more trick up its sleeve.

Even as Microsoft continues to support broadcasting standards around the world to bolster Media Center's support for broadcast television, the future of noisy, black 17-inch-wide boxes sharing a cramped cabinet with your stereo receiver remains in jeopardy. Indeed, the future of the living room PC may be sitting in your lap.

When Microsoft announced the Media Center edition of Windows XP, it was in some ways the desktop counterpart to the Tablet PC mutation. Whereas the Tablet PC was envisioned as a new form factor for notebooks, Media Center held the promise of transforming the desktop into its own new form factor. Indeed, in one of Bil Gates's final CES keynotes promoting innovative PC designs, he didn't mention desktops at all, referring to stationary computers as "entertainment PCs" in an AV component style.

But while a few companies continue to sell Media Center PCs explicitly designed for connection to a television -- among them Sony, Alienware, and companies targeting custom installers such as Niveus Media, the form factor hasn't taken off for a variety of reasons. Microsoft, in turn, has focused more on Media Center Extenders such as the Xbox 360 and HP MediaSmart Connect to bring the Media Center experience to the big-screen TV. And despite some technological improvements coming to help the cause, that situation is unlikely to change dramatically.

The past few years have seen a wide range of wireless technologies proposed to substitute for the now nearly ubiquitous (at least in terms of new HDTVs) HDMI connectors, but the dust is just starting to settle. Some proposals involve squeezing more juice out of 802.11n. Others rely on ultrawideband technology. Yet another that has many in the industry excited is from SiBeam, which intends to use the 60GHz band to deliver uncompressed 1080p video at 4Gbps. That technology, embraced by a group called WirelessHD, had received the most public support among major consumer electronics companies, with Panasonic, Sony, Samsung, Toshiba and LG listed on its site as promoters (and others listed as adopters).

But WirelessHD is still a ways from consumer availability and recently another wireless high-definition technology has attracted some heavy hitters of its own, including Sony, Samsung, Sharp and the cable set-top division of Motorola. Amimon's WHDI (Wireless Home Digital Interface) is different from many of its emerging competitors because it is designed, like WiFi, to be a technology that blankets the home, whereas most competitors focus on an in-room solution. WHDI even operates in the 5GHz band (like 802.11a and 802.11n), but sheds the costly bandwidth overhead WiFi utilizes to correct transmission errors. In contrast, WHDI is a "video modem" technology that attaches to a device's video output to send uncompressed 1080p video. After that, it's survival of the fittest for the bits.

The oldest of the "three screens" -- television – is generally far from the wisest. Sure, an endless array of set-top boxes and AV components packed with processors have appeared in the last few decades to use its screen as a surrogate, and now a high-definition, display for video games, PC content, Web pages, multimedia, videoconferencing and other entertainment. But while much television programming -- especially news and sports programs – has become cluttered with contextual trivia and tickers, the core TV viewing experience has remained stubbornly passive. Now, though, with backers citing the need to reclaim appeal from PCs and cell phones -- especially among multitasking kids, teens and young adults -- the first screen is fighting back.

Correctly recognizing that upconverting DVDs posed a serious challenge to high-definition discs, the backers of HD-DVD focused on the mandatory Internet connectivity of its players and support of it in some of its late content (the movie 300 was one of the best showcases). In HD-DVD's defeat, the Blu-ray camp has picked up the cause via BD-Live, part of the Blu-ray 2.0 specification. A forthcoming title that will take advantage of the Internet connectivity is Disney's 50th anniversary platinum release of its classic Sleeping Beauty. And it is not your wicked stepmother's princess.

With all the hoopla around the iPhone 3G, the finger has taken center stage as the input device of choice on the go. However, last week's column on the prospects of the Livescribe Pulse was actually the penultimate one on the subject of smart pens -- at least two alternatives have entered the market. Both are based heavily on reference designs from Israeli companies that have taken a different approach than Livescribe.

Rather than relying on a camera to read small dots on special paper, these pens work with practically any paper. And unlike the bulky Pulse with its ostentatious display, they are practically indistinguishable from normal pens and both come with software that can do a decent job of converting handwriting to text. The tradeoff is that some of the electronics have been offloaded to a small receiver that must be positioned on the paper, creating a two-piece solution.

IOGEAR's Mobile Digital Scribe, powered by Pegasus Technology, is a follow-on from a similar earlier product that required that the receiver be tethered to the PC. The Scribe can still function this way. In fact, when connected to a PC, the pen can be used to scribble (presumably for quick doodles, otherwise why not just use the keyboard?) just as its tethered predecessor could. Writing appears on an on-screen note that appears as soon as the writer begins to write, and the software can have these pages "float" on the screen as sticky notes..

The last Switched On discussed the innovative approach that Livescribe has taken in its core note-taking function while touching on some of the company's grander plans to create a wide array of applications and content, taking it far beyond its failed predecessor, the Logitech io2.

Livescribe is building an ambitious house in a neighborhood that has seen a lot of foreclosures; Pulse will need to rewrite history to be successful in the traditionally challenged smartpen market. Indeed, between the time that the Pulse was announced and shipped, Logitech announced it was writing off the market for now. In addition to improving on note-taking, the company points to the reduced size of the Pulse as being less obtrusive than previous smartpens and thus more appealing to use. One of the keys to smartpen use is that it is less obtrusive than, say, a PC using Microsoft OneNote, which also has the ability to synchronize audio to written notes.

However, the Pulse's OLED display offsets at least some of the gains made toward discretion by shrinking the pen's girth. Worse, to get the full benefit of the Pulse's cool ability to resolve conversations in a room using 3D audio recording, you must wear earbuds that contain embedded microphones. It's hard to imagine something that could be more off-putting to a speaker than seeing an audience member wearing earbuds, and it would engender curiosity when that speaker notices that they are connected to a pen. Fortunately, the Pulse does a very good job of recording even without the earbud-based microphones.

If the pen truly is mightier than the sword, Livescribe's Pulse smartpen ($149 with 1GB of flash memory, $199 with 2GB) may be able to take out a tank at 50 meters. Arguably the most technologically advanced writing instrument not intended for killing a Bond villain, the Pulse includes an infrared camera (for recording text), dual microphones, a speaker, a headphone jack, and an OLED display that can even play back short "movies" (animations synced with sound). And it manages to pack it all in a pen size that, while still a bit thick, is relatively comfortable and thinner than its closest technological ancestor, the now-discontinued Logitech io2.

Using its noise-canceling microphones and ink recognition system, the Pulse can be used to either take written notes that are uploaded to the PC, or record audio. But its greatest advance for note-taking over previous smartpen systems such as the io2 is the ability to synchronize written notes with audio. Simply put the pen into "Paper Replay" mode and tap on some text to hear what was being said as you scribbled. The result is the next best thing to real-time transcription. It can be used to check what may be an unclear or hastily scribbled note, focus on commentary while the pen captures the content, or create or copy a diagram while it is explained via audio.

But first, whatever is being written will have to be done so on paper designed explicitly for the pen. Like previous products that use Anoto technology, the Pulse needs smart "dot paper" to make transcription work. Without a doubt, this requirement will be a deal-killer for many, and limit the Pulse's everyday utility for some time to come. In contrast, simpler products such as the IOGear Mobile Digital Scribe uses ultrasound to track a pen's position and can be used on any paper (and the pens in such systems are smaller as well). To make dot paper more readily accessible, though, Livescribe will offer a template that should allow many customers to print their own dot paper at home. And dot paper enables the Pulse to pull off some pretty slick feats. Read on.

The first iPhone arrived at a time that suggested Apple needed to protect its iPod franchise -- but Apple delivered something that was much more than an MP3 player that could make phone calls. You probably won't be editing any iMovies on it for some time, but in the iPhone Apple has essentially delivered Macintosh 2.0. It's portable. It's affordable. It's connected. And it runs OS X, complete with its own breakthrough pointing device, your finger. Whereas the first Mac came with productivity applications MacWrite and MacPaint, the iPhone came with applications for Web surfing, e-mail, and consuming media, the evolution of what much personal computing has become.

Furthermore, Apple has shown that it has learned from mistakes it made with the first Mac. Whereas early monochrome Macs were a tough sell for game developers, Apple has highlighted games as some of the most impressive early third-party applications for the iPhone and iPod touch. And whereas Apple was notorious for keeping Mac prices high for many years, the next-generation iPhone takes advantage of carrier subsidies for an out-of-pocket price of $200 in the US (and even less or free in some countries). Despite the many changes that have transformed the software industry since 1984, the iPhone, along with its SDK, development tools and app store, have the potential to bring the work of OS X developers to millions of people who don't own Macs -- that is, if Apple lets them.

The last Switched On discussed the traffic-fighting prowess of the Dash Express, now available for only $299. Its leading ad hoc local information querying and traffic-finding capabilities represent the best potential to transform the portable navigation device from a product used primarily for unfamiliar terrain, to an everyday tool to expedite getting to point B.

When it debuted online at Amazon, it shared prime real estate with another transparently-connected consumer electronics device: the Amazon Kindle. But besides their completely divergent uses, the Dash carries more than the weight of a couple of extra radios in its cranium. The unfortunate part of the Dash Express is that the device's unusual size takes up a good chunk of windshield real estate and, of course, serves as an even larger advertisement to thieves.

Dash has the ability to remotely kill stolen Dash Expresses, but there is still the risk of a break-in. In many ways, Dash's service is a better match for an in-dash navigation unit such as the Pioneer AVIC series, but these expensive devices represent a small fraction of the navigation aftermarket.

What do you get when you cross a portable navigation device and a cellphone? Dash Navigation's answer is the $399 Dash Express, the most credible attempt yet to crack the ancient driver conundrum of figuring out what's nearby and the best way to get to it. In doing so, it stands to elevate the portable navigation device from a glove compartment shut-in to a mobile mentor -- one that Dash hopes that customers will find valuable enough to justify $10 (or more) per month on a service fees.

Dash's cellular connectivity enables it to take a hybrid approach to traffic information. Routes for which Dash has available information are marked with either green, yellow or red lines depending on the heaviness of the traffic. Solid lines indicate that the data has been supplemented by the Dash driver network – cars that have Dash units sending information upstream in real time. Dashed lines convey information that Dash picks up via its historical traffic pattern information provider Inrix. Dash claims that it needs about 1,000 units in most cities to cover major routes, double or triple that for the largest US cities such as New York or Los Angeles.

Even with its emerging network, the Dash Express is surprisingly effective at routing around known trouble spots on the fly. And while it occasionally failed to pick up on congested stretches, on several occasions it was so accurate as to the emergence of traffic that the route turned red just as conditions forced the car to slow to a crawl. Even at its early stage, Dash certainly proves the concept of the traffic-routing prowess of a "live" GPS device.

The last Switched On discussed GreenPlug, a startup that is trying to create a new standard for universal AC adapters. The environmental benefits GreenPlug offers are enormous, like the reduction of power caused by keeping energy flowing to a fully charged device, and the great reduction in waste currently caused by the need to keep manufacturing, shipping and disposing of the billions of AC adapters produced every year (many of which are practically wed to a single product).

Even without GreenPlug, there has been significant movement over the past few years toward the acceptance of the mini-USB port as a connection standard for portable devices. Sony, for example, now offers USB charging on devices such as the PSP and Sony eReader, where others previously required proprietary adapters. The USB Implementers' Forum is working on new guidelines to ensure better compatibility for chargers and devices using the popular port that was designed first for data transfer. And there is now legislation in place in China that mandates that any phone sold there must enable USB charging.

However, USB has limits in terms of the wattage that it can deliver and can't charge, for example, notebook PCs, as well as many camcorders, digital cameras, and other products. Nonetheless, in a nod to the growing momentum around the USB connector for cell phones and other low-power gizmos, GreenPlug has designed its connector to resemble a mini-USB port. A GreenPlug adapter can charge mini-USB products that don't have its chip, even though it won't offer power-saving benefits in that circumstance.

The best and most popular portable electronics products don't work for long without them, but the general consumer sentiment toward AC adapters is evident in the terms of endearment such as "bricks" and "wall warts" given to them. They're referred to with even more colorful language when they're accidentally left behind on a trip or are otherwise unavailable when needed.

But if a startup GreenPlug has its way, future portable electronics products may not come with an AC adapter, much like many printers today don't come with a USB cable. With engineering talent that ran design for Apple's DC power systems for the iPod and the MagSafe connector, GreenPlug is taking on one of gadetry's holy grails – a universal connector that can work on practically any portable electronics device. GreenPlug would turn the frequently forgotten and mismatched AC adapter into an accessory ecosystem. The company envisions DC charging hubs that would be available in conference tables at the workplace and in tables and walls at coffee shops.

The US smartphone market may continue to be dominated by mobile platforms from Apple, Microsoft, and RIM, but Linux has been creeping into ever more mobile devices in the last few years. Some Motorola RAZR 2 models have donned a Tux, Palm is looking to Linux to drive its next-generation consumer smartphones, and Android's backers hope to spread it to an even wider array of handsets. Linux is also driving many avant garde connected consumer electronics devices such as the Chumby, Nokia N810, Amazon Kindle, Dash Express, and whatever the fertile minds tinkering with Bug Labs' modules are envisioning,. Even the remote control that houses the user interface of Logitech's Squeezebox Duet is a Linux computer.

However, none of these products is intended for as flexible a range of uses as a notebook PC, where Linux is being tested as a tool to achieve lower price points on a new generation of low-cost but style-conscious ultraportables. ASUS set the pace with Xandros on the Eee PC, and HP has tapped Novell SuSE Linux for the 2133 Mini-Note, but whereas the Eee's positioning has been somewhat of a loose hybrid between an adult OLPC and the Nintendo Wii's culture of global inclusion, the HP Mini-Note has been strongly focused on reckless, immature students while acknowledging potential for senior executives that have been known to share their temperament.

Last Switched On introduced the Slacker Portable, a device that is as noteworthy for great value in bringing a steady stream and great variety of free music -- including on-demand favorites from those with a premium subscription -- as it is for its design quirks.

None of these are as frustrating as the device's touch strip used to provide quicker access to on-screen selections. Unlike the touch strips on older Creative Zen models, it uses absolute positioning that activates the button at that part of the screen. Unfortunately, this means that stray touches can cause the interface to jump from screen to screen and even skip tracks. The Slacker team may have considered the touch strip a compromise for a device without a touch screen, but at some point realized that their implementation wasn't up to the task. Slacker turns the touch strip off by default, and it will need a major overhaul to prove useful in future players. Fortunately, the jog dial Slacker includes is almost as efficient.

Other controls fare better as they represent hardware counterparts. The device's left side has a Favorite button (which designates that a track be played more often) and a Ban button (that prevents it from being played again in the future); its right side has the Skip button, which Slacker sees as a key differentiator from satellite radio. Most station management tasks, such as creating a new station or designating which stations show up on the device, need to be done from the Slacker site or desktop application.

The Slacker Portable is the proverbial elephant being inspected by blind men. One is the crop of portable MP3 players, to which the device's service represents free, fresh music on the go in exchange for user control of track selection. Another is the bevy of online internet music sites such as Pandora, Last.fm, Finetune and others, to which it represents the leap from the beb to portable entertainment. A third is the traditional consumer electronics industry for which it portends a connected future. And a fourth are XM and Sirius, which now appear on track to merge in part due to the kind of competition that the Slacker Portable will ultimately provide.

The Slacker Portable picks up where last year's promising Sansa Connect left off. While that device was billed primarily as an MP3 player that boasted tight integration with the Yahoo! Music Unlimited service (now shuttering), the Slacker Portable is labeled as a "personal radio". MP3 files can be loaded onto the device, but that feature is more of an afterthought.

The device comes in three capacities that are billed as storing a different number of stations, which are either genres preset by the internet radio service available at slacker.com, or customized for the user based on a particular artist. One nice touch is that a device ordered from Slacker comes pre-populated with any stations you have set up on the site.
