The Pogoplug is a nifty little device that attaches to both your router and any USB hard drive (or thumb drive) and turns the drive into a NAS (Network-attached storage) device. Then you can share files with any computer hooked to your network, or even over the Internet, for those times when you need to download files on the road. There’s even an iPhone app which can be used to shuttle files back and forth. Looks incredible easy to set up. You can pre-order one here for $79 (ships in March).
