Looks like the press has confirmed something which I've noticed the last week using Vista: iTunes doesn't work on Vista. In fact, I've seen the blue screen of death 3 times attempting to play a Quicktime video, and starting up iTunes may or may not work.
The last time I tried it, Vista crashed again. Is this a ploy by Apple to discourage purchasing Vista? Check out this quote :
"Apple said iTunes may work with many Vista computers, but the company knows of some compatibility problems and recommends that users wait until it resolves the issues with an iTunes update in the next few weeks, the company said in a statement provided Friday by spokesman Derick Mains."
