I discovered almost by accident that Stream is a Microsoft Certified Partner, and as such, gets access to discounts on Microsoft products. I managed to register with Microsoft as a member of Stream, and snagged Windows XP Pro (and a nifty XP lava lamp) for $52.00. Not too shabby considering it retails for 300 bucks.
Feels kinda weird perchasing an opperating system. I haven't done that since DOS 5.0 ;)
