smallest USB 3G modems look like grossly over-sized thumb drives, while the biggest ones sport hinges or fold-out antennas that serve as tripwires for absent-minded businessmen with venti frappuccinos walking by your tiny little coffee shop table. Huawei's E583X detaches all that bother, acquiring a 3G wireless signal and then beaming it out again as WiFi, meaning you can leave it in your pocket and get a double-dose of microwaves. It sports a 1,500mAh battery, giving it five hours of independent living, and in emergencies it can act as a tethered modem as well. Sadly this first version will only accept a single WiFi connection, but future ones will allow four others to mooch your data plan. That it also blinks randomly like a prop out of Star Trek's utopian future is just an added bonus. It's set to light up Europe next month -- likely with some hideous contracts attached.
