iOS and Mac OS X will never be equal
Who wants a laptop/desktop without the productivity you get in current OS X or Windows? I love my iPhone and my dad's iPad, but I'll never be able to use photoshop, illustrator, or even the MS Office apps on either device. You need the peripherals of a mouse, keyboard, and pen tablet. Sure, it's POSSIBLE to do some light work in those kinds of apps, but it's really not practical. Apple would need to go a long, long way to getting me to ditch an OS like OS X or Windows.
