I've been looking into .Mac, since I'm looking into an iPhone and I hear that the .Mac mail works the best with it. I also understand that it will keep my mail, calendars, and contacts up to date between my two computers (and iPhone if I get one) I have been looking for a way to keep files in sync between my mac pro, and my MacBook Pro. I am on the road....a LOT, and I have some important things I need to keep synced between the two. Mainly my business files, and my Quickbooks file. Is .Mac intellegent enough to keep the most up to date version of the same file on both computers? Say I make some changes in Quickbooks on my Mac Pro and then i'm on the road and want to see them in my MBP. Then I update something on my MBP and want to see it on my MP. Will it keep single files in sync? Thanks!
