whyTunes
The only reason I ever installed whyTunes was because I got a $50 gift card for it. After 16 months, I *still* have a little over $4.00 credit on it. Goes to show how much useful product iTunes has. (and I had to install it inside a MSWin7 test VM, since it doesn't run under Wine or Crossover Office).
But have to uninstall QuickTime for MSWin???? Gee, all your Future Vision Multimedia CDs are gonna stop working...
