I'm seriously considering the new 2011 13" 1.7Ghz MBA with 128GB SSD. Currently, I have a 2010 13" 2.13Ghz MBA with 256GB SSD. The plan is to swap the SSDs when the 2011 arrives, and then hand-me-down the 2010 (now with 128GB SSD) to the girlfriend, as she does not even use up the 80GB HDD of her old WhiteBook. On my side, I'll save re-configuring a virgin install, as I have many many specific hacks and such (mostly for development purposes) that the Migration Assistant wouldn't be able to move over; plus a BootCamp partition that's perfectly configured. In addition I save several hundred bucks. So my question is -- is this possible? Can I just move the SSD over like that? I know I'll need a special screwdriver to open the case, but otherwise it seems straightforward at least on the hardware side. The other thing is, would that void the warranty on the machines to open them up and swap the SSDs?
