Just a guess – but I’m feeling that with the rumors of the AppleTV getting the iOS treatment, the Mac Mini becoming more home theater “friendly” and iOS being renamed, we’re going to see iOS or some sort of iOS emulator (which we kind of already have) in every Mac sold in the not-so-far-away future. Couple all those new Macs with a built-in A4 processor and an OS X 10.7 EFI fast-booting iOS experience, and you’ve got a mobile (or home) theater that sips power, making that 10 hour laptop battery last 10 times as long.
Gimme gimme gimme.
