My parents are trying to get their contacts and calendar entries to automatically sync across their two iPhones, one iPad, and two Windows computers. Using MobileMe they now have the iOS devices syncing well over the air, but the Windows machines are hit-or-miss. They’re thinking about switching over to Macs, though it would be a major investment of time and money. But they’re only interested in doing it if it would mean that the MobileMe syncing would actually work, so that if they add or change a calendar event or contact entry on any one of the various machines, it would automatically update, over the air, on the others. Is this likely to work? How good is Mobile Me syncing between iOS devices and Macs? Please help. Thanks.
