I have two PCs that I am always sitting at when I am home. One reason I bought the iPad was to very deliberately force myself to stop sitting in my computer chair all the time. I can use it in bed, I can use it on the couch, I can carry it from room to room, I can prop it on random objects. But maybe that's not for you. Everyone's life is different. At last we begin to glimpse the future of computing, the one we have been waiting for: Where recommending a computing device to someone is going to be like recommending a brand of underwear. There are going to be special-purpose computers for everything. Already we have special computers just for music (the iPod Shuffle), special computers just for reading (the Kindle), special computing hardware just for making you exercise (the Wii Fit)... if anything, the iPad may be more of a general-purpose computer than one can expect to see in the future. It's like a device for prototyping the single-purpose computers -- which will, of course, no longer be called computers -- that our grandchildren will use.
