This is what you get when you mix Steve Jobs' iPad presentation with yesterday's MacBook Air presentation, barely 10 months later. Of course, a PC netbook is not like an axe-blade-thin MacBook Air. Also, a MacBook Air is not "cheap".
Let's take a bet: Despite saying the contrary yesterday, Steve Jobs will show fully touch-enabled notebooks powered by Mac OS X Lion in October 2011.
Hey, I predicted all this a few months ago, so my touch-crystal ball works. And with touch-crystal ball I really mean "whiskey touch-glass".
