Best USB Gadget Yet: Desktop RC Mini-Car

This tiny RC car from Japan's Solid Alliance comes with its own garage, which plugs into your PC via USB. When the car is inside, it charges. But when you want to take the car for a spin, you CONTROL IT WITH YOUR KEYBOARD. The garage doubles as a wireless transmitter. It even makes a revving engine sound. Here comes the VIDEO!

Worst USB Gadget Yet: Annoying Dancing Robot

Solid Alliance also puts on sale tomorrow its USB Dancing Robot. This hideous plastic object connects via USB, and spazes out every time your PC makes noise. When music plays, or you get new e-mail, or when there's a PC "event" with an associated sound, the dancing robot MAGNIFIES THE ANNOYANCE.

New TI Calculators Sport Colors, Stickers

Texas Instruments rolled out today a new line of calculators that emphasize "teens' sense of style." The TI-84 Plus Silver Edition graphing calculator comes in FIVE COLORS: blue, teal and three shades of pink, plus customizable GraphiTI slide case decals. If that's not enough to get kids to love math, interchangeable faceplates are available in 14 colors. Other TI lines come in fruity colors, too. 'Cause that's why kids hate math: The color of their calculators is too boring.
