Spotted this at Gizmodo. You can get a free copy of Windows Vista Ultimate, Office Ultimate, Money Plus Premium, or other software, all for the price of letting MS track your computer usage for 3 months. That includes surveys every 2 weeks. It all stems from Microsoft’s Windows Feedback Program. To be honest, I am in for this as I wanted a legal copy of Vista. All MS will find out from the PC they track is that my wife loves Diablo II.
edit: Looks like they are all done with this…supplies didn’t last thanks to /. and Gizmodo.
