But you need a PC to use an iDevice!

Given that they need to connect to a computer running iTunes their desire to lose the computer isn't going to work.

Also, when I can plug in a proper keyboard, 2 large cinema displays, local storage, run desktop applications, connect optical and USB drives then an iPad *might* start to become semi-useful but the horrid amount of clutter it would generate to enable that means I'll stick with my Mac Pro and MacBook Pro for the foreseeable future.
