Who said anything about a supercomputer? If you put all of the components of a modern iPhone into a wristwatch except for the screen, you get a device that's more than capable of running for days on end. Sometimes you'll connect through a headset, sometimes input through a keyboard, and often you'll access it through displays of various sizes. Wireless, of course, with something like WiDi. You talk about the watch like it's inherently got to have a slow CPU and short battery life. But it's the display that's the single largest consumer of battery, and the CPU is relatively weak in an effort to compensate for that. On top of that, a leather or plastic band is a complete waste of wrist real estate that could be put to use as batteries or sensors or anything else. A device like that could be your watch, phone, tablet, laptop, TV, smarthome remote, fitness tracker, and wallet. The wrist device shouldn't be an accessory, everything else should be an accessory for the wrist device. Your comments about cloud storage and data centers is no more relevant to this topic than it is in any other. There's nothing mutually exclusive about "headless" wrist computers and the cloud. Obviously with a data connection, your wrist device would in fact be your always-present connection to that remote data center.
