>I don't say that handheld devices won't be widely used, I only say that they won't replace PC's.

There are estimates of 2billion cell phones world-wide. Of those, the majority are in underdeveloped nations where the populace can't afford to purchase desktops. The estiamtes say that they will use the cell-phone to access the internet, email, etc. I doubt that there are 2 billion pc's in use in the world.
