Assuming you have a built-in slot, is it feasible to install Windows 7 (Vista, or XP for that matter) onto a 32gig SD card? By install, I mean house your windows folder and any OS required folders and files on the card. Program Files and User directories could go elsewhere.
If so, what specs do you need to consider for the card and would their be any major drawbacks?
Update
For the sake of argument, my target machine would likely be a Dell Inspiron 1720 which has a built-in SD slot. The A9 BIOS revision can boot from that slot, USB or the ExpressCard bus.

It's definitely doable, but there are two concerns that you'll need to address if you want to boot and use Windows 7 off of an SD card regularly.
