SMS M500 Watchfone -a mobile phone on a wrist As mobile phones have shrunk in size, so one boffin or another has invariably thought "at last, it's small enough to strap onto someone's wrist and call the thing a watch phone!" The result has invariably been a frankenstein-esque device that looks remarkably like a mobile phone bolted onto a watch strap - in other words, more phone than watch, and not at all what you want hanging on your wrist.

Finally, though, all that's set to change as mobile phone technology has at last reached the size where it can be incorporated into the dimensions of a watch and so actually look like one. The proof is this, the SMS Watchfone M500, from Australian company SMS Technology.
