For the road warrior, mobility and accessibility are key. Grayson Ashley, author of “Computers to Go,” recommends an iPhone  for total lightweight portability if you just need e-mail access and Web surfing capabilities. But most likely you need a little more than that, and laptops don’t get much lighter than the Fujitsu LifeBook U820 mini-notebook, which weighs in at a mere 1.3 pounds. With Windows Vista, touch screen capability, and a long battery life, it’s a great choice for the mobile professional who needs to pack light without sacrificing important functions and features. As a bonus, the built-in Garmin Mobile PC navigation system allows this laptop to do double-duty as a GPS system that will keep you from getting lost, no matter where you wander. The optional Bluetooth feature lets you easily transfer data back and forth to your PDA, cell phone, and other gadgets. The fingerprint sensor keeps your data secure while you travel, and the built-in Webcam lets you maintain face time with colleagues and clients.
