Couple of questions for anyone who may have tried this. I'd like to put Windows on my new MBA (2011, i5, 256GB). The SD card slot is sitting there unused, so I'm wondering... would I be able to put Windows 7 on a 32GB SD card? Would that even be bootable? And fast enough for general use? I could always partition the internal drive, but if there's some other avenue, I'd rather keep that whole drive for OSX.
