I purchased this for my wife and have been trying all week to install this on a Windows XP desktop and on a Win 2000 notebook.The installation was horrendous! It caused my WinXP desktop to reboot itself whenever I tried loading iTunes. When attempting to sync I get the Do Not Disconnect warning. I cannot get it to go off. Just about when I was ready to throw it out the window, I saw on the apple.com website hundreds of posts from people having similar problems. It's impossible to find a number to call for tech support. You'd think that something that cost this much would have a live person to talk to...if I can't get it to work in the next few days, I'm going to return it for a refund.
