I just upgraded my iTools account to .Mac a few minutes ago. OK, correct me if I'm wrong, but didn't Steve say something in the keynote about being able to synch the files on two or more Macs using iDisk? I thought I would be able to do this doing Backup, but it turns out that if I backup my iBook, then backup my iMac, it completely erases my iBook backup! So basically you can only backup one computer at a time to your iDisk! Please tell me that I'm missing something here - otherwise, this Backup stuff is entirely useless to me.
