I'd go the 13" MBP + AppleCare + higher processor speed option if they have one for the 13". Not sure if that goes over your $1200 budget or not.
That's assuming you want a laptop and you don't need a high screen res, and you're not doing heavy work.
I'd not go with whatever a blackbook is, not that I know what it is, but my puter-sense is going wild! danger!
I'd not get the blackbook if it runs windows, but that's just me. Still don't know what it is though.
Kind Regards
