Mark my words. It'll take Apple until 2012 to figure out that the 3.5 display is too small and that anything under 4.0 inches is. Apple is always lagging behind common sense 2-3 years because they have rich and lazy hardware design management who don't think. Look at the fugly bezels around the iPhone, iPad and all the Macbook Pro's and Air's. They really could be used in an encyclopedia as the definitions of unpractical and therefore bad design.
My 13.3" Macbook Air could house a 15.4" monitor without changing its footprint. My friend's 11.6" Air could house my 13.3" display without changing anything else about it, making it the ultimate road warrior.
But what does Apple do? They add this ridiculous tapering to make the Air "seem" thinner than it already is, thereby making it impossible to put in displays that fill the entire footprint of the laptop and are practical.
Going away from the Air, who wants heavy fragile glass panels on their laptop screens or phones? Nobody in their right mind. It's ridiculous on a mobile device, and they're going to phase it out, but they have too many established brainless guys in their management who can't admit their mistakes and keep clinging to the stupid design ideas until it becomes blatantly obvious that it was stupid, years later.
Also, that black fat bezel idea on all your products was wrong and you should get over it Apple. Just get rid of it. Nobody wants a bezel when they can have a larger display instead.
The only reason this company still exists is that nobody else has the balls and/or money to start a serious competitor using UNIX-based OS.
