So I have been a longtime MobileMe user. I use it primarily for 2 things: 1) iDisk (obviously this is gong away...) 2) Syncing contacts between 2 macbooks (both on 10.5.8) I have an iPad and am looking to get a 4S. If I migrate to iCloud, will I lose my ability to sync contacts on my macbooks? As of now, I'd prefer to not upgrade to 10.6/10.7 as there are some older (rosetta) programs that I can't afford to upgrade (Aperture 2.1.1 and Adobe CS). Thoughts?
