What it is: A USB adapter that lets you connect your computer wirelessly to peripherals such as printers, cell phones, and MP3 players using the Bluetooth short-range wireless protocol.
Why it's cool: Imagine what your desk would look like without that tangle of cables and wires running to the printer, the mouse, the scanner, etc. Belkin's device makes that possible. It supports up to seven external devices.
Drawbacks: Those devices have to be Bluetooth-capable, which could mean that you need to buy new versions of all your peripherals to get the full benefit. Adding any wireless technology brings with it security questions.
Price: $49.99, www.belkin.com
