I've been looking into developing for Xbox and kinect, but I keep reading you need Windows vista or 7. Is there a workaround or anyway to use either a Mac, Linux, or Windows XP? I've tried to install XNA Studio and everything on XP, but it tells me to upgrade. I'd really rather not drop $150.
If you search on this page for Standalone you'll see a download link. This version lacks the windows phone set which required Windows 7.

You can make xbox games, and kinect games for PC, but you can't make xbox-kinect games yet.
