Re: That side-on picture of the phone looks just like...
That's because you obviously consider a wrist watch to be an item of jewellery for showing off with.
Wrist watches were clocks invented for the Navy, depth gauges and Altimeters followed suit by conveniently being wearable on the wrist.
At some point in the future, when all of our tech can be miniaturised to the size of, errrr, a wrist watch lets say, there's going to be a clash of interests. Although I imagine a complete nobber somewhere will wear a Rolex on one arm and computer/communicator on the other though. Either that or stay in the dark ages carrying a slab around in the pocket.
