I'm old enough to remember a time when minicomputers and mainframes were where 'serious' computing was done. Microcomputer platforms like Windows and Linux gradually cannibalized their way up until practically nothing was left. It seemed impossible and stupid at the time but it happened. I'm not predicting that mobile platforms will make the same inadvisable climb, but I'd be a little surprised if they didn't.
