I bought a new Ipad, 16gb, 3g, and as my laptop was out for repairs (windows vista), I synced to my old desktop (XP) so I could get the Ipad up and going. I had used the laptop Itunes to snych my Ipod Touch. When I plugged the Ipad in to my repaired laptop, the message is that you can only synch to one Itunes, and do you want to erase all on the Ipad and add the stuff from the Itunes in the laptop. I have bought apps for the Ipad since I last synched my Ipod Touch to the Itunes. I got no question about transferring my purchases to the laptop. I think I got that question the first time I synced with the old desktop. Do I have to lose the apps that I added before this second sync? And, (boring aren't I?) how do I take the old desktop off the number of computers I have added to Itunes? There is a max of 5, and it says I am at 3.
