50% off Windows 7 Upgrade till July 11

So for $50 you can get Home premium or for $100 get Windows 7 pro. Not bad but the fact I got Windows Ultimate and it was a complete waste of money doesn't fix the $229 upgrade for it. Why does Microsoft sell Ultimate when its a Ultimate waste of money? Really the Ultimate upgrade should be reduced for us. We spent the cash on Vista Ultimate expecting more then a few new wallpapers and software that doesn't work AT ALL. Main reason I'm moving away from Windows. I just feel screwed over.
