Today Kempler & Strauss launched their W PhoneWatch gadget which they claim is the world’s smallest full-function quad-band GSM cellphone watch, and given how small the market is at the moment, it’s not that difficult a claim to make. The W PhoneWatch features a 1.5-inch touchscreen interface that can be operated with your fingers, eliminating the need for a stylus, as well as an impressive set of features for a watch-sized phone including a digital camera (640×480 stills or 128×104 videos) and a microSD card slot.
