We've seen some cool iPhone docks, like JVC's surround sound speaker dock system, but the Buffalo Dualie takes the crown for the most useful, why-hasn't-someone-done-it-yet device.
See, it's a portable hard drive clocking in at 500GB, but it's also a docking station that allows you to sync media files between itself and your iDevice.
The Dualie is actually made up of the docking bit which has a two-port USB hub, and the HDD itself, which comes with one USB and one FireWire port for data transfer. Unfortunately (or not, if you're a Mac-olyte), the hard drive is Mac-formatted, so only Mac users can make use of this nifty little gadget.
Buffalo Dualie comes with adapters for iPhone 3G/3GS, iPod touch 2nd Generation, iPod classic and iPod nano 5th Generation, and is available exclusively at www.apple.com or the Apple Store from February for £199.
