JetFlash 110

With its refined zinc alloy body, this 8GB stylish jump drive allows you to download all the information you could ever need from your PC and bring it with you. It measures only 49.5mm long by
15.8mm wide, and it is so thin (7.4mm) that it slides easily into tight-fitting stacked USB ports. A short chain enables you to hook it to a key ring, or it’s compact enough to store in your wallet. $148, www.transcendusa.com
