What general computing tasks are you referring to? Most people's daily computing tasks involve web browsing and email or social networking, things the iPhone does and presumably iPad will do quite well. Also what is wrong with touch displays? 10-20 years is a very long time in terms of computers! What do you see as the future of UIs? To me, touch is more intuitive/easier than using a mouse for most things. The interaction you can get with multitouch pinch/pull, swipe, etc allow for rich new possibilities in UI design.
