    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.

    Some say it will run hellishly slow off an SD Card but I am going to try.

    On the fence
    SD cards are limited to USB 2, and are slower than you want a boot drive to begin with. It is possible, but not something you want to use for anything more than basic tasks.

    Another option would be to install Windows on your main drive along with Lion, and use the spare 32GB card for file storage.

    EDIT: Saw the last line of your post. I still think this is the best option though, if you really need to have Windows...

    Just for fun I spun up an Ubuntu VM under Parallels on a 32GB SDHC card. Was not even usable (didn't time it, but took over 5 minutes to boot). Took over a minute to launch an application.

    With your 256GB SSD you have more than enough space unless you have a TON of application. I have a 20GB Parallels volume for Windows 7 and I think I have ~10GB "free".
