The Watch-Phone

This is really hot! This is not the first time useful electronics have been reduced to be able to fit on the wrist, but this is certainly an improvement on the watch-radio,watch-calculator, etc.
The LG-GD910 comes in a curved metallic case that straps onto the wrist like a watch, uses a 1.43-inch touch screen, and moves data at snappy HSDPA speeds.

It will offer other features, including a camera for video calls and snapshots, a text-to-speech engine for voice dialing and composing text messages, a built-in MP3 player, and Bluetooth. Plus it is water-proof!!!!
