While I fully expect "cloud computing" to result in the same resounding THUD as did earlier Paradigm Shifts (the network is the computer, etc), I think Old Doc Jobs is trying to take a look over the next hill at where computing for today's non-computer-geek/non-computer-professional/non-power-user computer users will be in five to eight years. He's decided where he thinks that will be, and he's pissing in all the corners of that particular property so that he and his progeny can milk it for all it's worth. It's not so much what the next paradigm will be, but the fact that there WILL be a next paradigm of some sort or other. I expect to be using a PC (Mac, actually) until they pry it from my cold, dead, fingers, but that's on my professional side. As a personal user, I am keeping a close eye on iPad because I think it's got a chance of morphing into something really useful. People have been calling Jobs a fool and an idiot for years, and he's still standing and still doing some good work. I'd not bet serious money against him.
