Fine, let’s have a device the size of a cigarette pack that holds all the computing power. But then I need a trackball to relieve my “mouse elbow,” a keyboard because my business is editing tech docs, and TWO monitors (big ones) because I’m webmaster for a small private school in Palo Alto and a bunch of yoga-related sites. And I’m never, ever on the road. (Sorry, but the library is just too noisy to work efficiently.) Despite the obvious appeal of tiny devices that can do many things blazingly fast, there are task for which they will always fail, fail, fail without an adequate human interface.
