ThinkGeek Personal Soundtrack T-shirt

$40; thinkgeek.com

A product that started off as an April Fools’ Day prank for the users of a popular nerd-culture mail-order site has become a reality. The Personal Soundtrack T-shirt has a speaker built directly into the fabric. The sound is controlled by a wired remote, which gives the wearer several pre-programmed options ranging from a victory theme to a rim shot. The fake product’s page received so much enthusiasm from potential buyers that ThinkGeek has put it into production.

Bluelounge Sanctuary

$129; bluelounge.com

Increasing the size of your portable electronics arsenal means a new gadget to play with. But it also adds to the unwieldy tangle of charging cords cluttering your desk. The Sanctuary offers an ergonomic and stylish, if slightly pricy, solution. The underside of the tray has 12 built-in connectors compatible with most popular MP3 players, cellphones and GPS units, all of which funnel down to a single cable, virtually eliminating the need for stand-alone chargers. There’s even a standard USB port, should you have a device that isn’t one of the 1,500 supported.

Nike+ SportBand $60; nikeplus.com

Until now, if you wanted to use Nike’s elegant running-stats system, you needed an iPod nano. The SportBand takes Apple out of the equation, opting for a stand-alone USB device that plugs into a durable aerodynamic bracelet. Info about your run is displayed on a monochrome display and, plugged into a computer, it automatically uploads workout data like distance and pace to your account at nikeplus.com. There you can track your progress and compare results with other members. There’s even a virtual coach to help you hit your goals.

HP 2133 Mini-Note $500 and up; hp.com

HP’s press release suggests that its new pint-sized Windows machine is designed for students, but its slick aluminum chassis, low price and 21/2-pound weight should make it attractive to anyone addicted to public WiFi. While some users may miss the DVD drive (it’s available as a USB add-on), the 2133 offers higher storage capacities than other, flash-based machines and the 8.9-inch screen’s 1,366×768 resolution significantly reduces the need to squint while browsing the Web. Plus, it’s got a full-size keyboard.

Sony HDR-TG1 HD Camcorder $900; sonystyle.com

Diminutive cameras such as this, generally sacrifice features and picture quality to maximize portability. But Sony’s latest shooter promises full 1080p resolution in a box that weighs less than three-quarters of a pound. This cam, not much bigger than a pack of cigarettes, also sports an impressive 2.7-inch touch-panel display. The sensor captures HD video, as well as 4-megapixel still images utilizing the facial detection system, which ensures your subjects (not the background) are in focus. It all comes wrapped in a sleekly rugged titanium case.
