Macs are not especially relevant to Apple revenue at this point. iPad plus magnetic keyboard is getting pretty close. Still not sure that better multitasking would push me over the edge to not wanting a MacBook for serious day-to-day multitasking work.

I do think they're trending in that direction but I actually like that they're not pushing people faster than feels comfortable. I expect to see a convergence of iPads and at least MacBook Airs but we're not quite there yet.
