So I have my iTouch synced with iTunes, iCal and Address book on my iMac (that's a lot of lowercase i's). But I use two computers. How can I sync my iCal and Address book from the iTouch with my Powerbook? Evertime I try it warns me that it's going to erase all of my apps and other stuff on the iTouch. Is it possible to have the iPod Touch synch with more than one computer? Oh, and I don't want to set up a .Mac account.
