I think this is a very narrow view of it all. At the risk of sounding like someone who has drunk too much of the Apple kool aid, here's the big picture potential of all of this together... If apple makes this a cohesive environment. Download, Launch apps, and full screen modes, then we are looking at the next step past the window/mouse GUI -- at least for the masses. iOS and the iPad has been successful in part because of how simple it is to use. Touch metaphors make a lot of sense to non computer people. Not sure if it necessary makes as much sense abstracted to a trackpad interface but certainly one window at a time is much easier for novices to understand. Think of the mom test where I want to talk my mom through installing an app. It's crazy how hard it can be with freely floating windows and disk images and downloading off the internet. App store and launched interface? I think this could be very big. Now that said this sort of interface simplification has been tried for years... So we will see if it sticks this time.
