Your PC in 2008 and Beyond

Kiss Your Power Cord Good-Bye

You hardly think twice about connecting your wireless laptop to the Internet, but you still have to fumble for a power cord when your battery runs out. How quaint. Soon all those cumbersome power bricks will be just a footnote in your grandchildren's history books, as wireless charging comes to market.

What is it? Currently two ways to accomplish wireless charging exist. Inductive charging works by matching the resonance of the charging pad's electromagnetic field to that of the battery, allowing the battery to charge over a small physical gap. In contrast, conductive charging passes electricity directly between two surfaces in contact. Which method will win out is not yet clear, but in either case you'll be able to simply place your laptop, phone, and music player onto a universal wireless charging pad that will immediately begin juicing them up.

When is it coming? Next year both inductive and conductive charging technologies will emerge onto the market, but most devices will require a $30 adapter to work with them. WildCharge expects to roll out its first conductive-charging notebook product (paired with a compatible notebook) in time for 2008's back-to-school season, while eCoupled is pushing to get its inductive technology into cars, countertops, and desk surfaces by 2009. Look for wireless charging to become commonplace in 2010, after major phone and laptop vendors sign on to support it.

Print From Anywhere (and Anything)

Forget about running home to print out your photos or--gasp!--ordering prints online. The next generation of mobile devices will come with their own built-in printers.

What is it? Zink (short for "Zero Ink") Imaging, a spin-off of Polaroid, has been working on a new way of making photo paper. Zink paper has a crystal substrate sandwiched between its layers that colorizes as it passes through a slim-profile printer. The printers themselves are so small that you can slip one in your pocket, and they can easily be built into cameras, laptops, or other devices.

When is it coming? In 2008, Zink will partner with a major camera vendor (name not announced) to release the first pocket-size digital camera with a built-in printer. This early model will produce 2-by-3-inch photos. At the same time, the company will begin selling a tiny handheld printer (probably for about $99) for camera phones; it'll print adhesive-backed photos that will likely grace the school binders of many eighth-graders. Two or three years after that, the technology may be integrated into laptops and other mobile devices.
