I’ve been getting a lot of questions of late about Apple’s transition from MobileMe to iCloud. Unfortunately, I don’t have a lot of answers because Apple has not yet posted a lot of details, but they did post this page with more information.

The short version is, you don’t have to worry too much about it until June 2012, after which you will have to make the switch. Presumably, by then, they will have worked out both the details and the kinks.
