The other unmentioned thing is how Apple will approach the cloud.  That massive data center they're building can't just be for streaming music and video to iTunes customers.<p>I bet you see iPad evolve into Apple's cloud computing platform while the OSX-based notebooks stay they way they are.<p>This also has some serious long term problems for Mac OS.  What if Apple decides (or has already decided) that the future is closed-architecture cloud computing devices?  You'd see OS X (OS XI?) dead before the decade is over.
