According to someone at an Apple retail store, MobileMe and previous generation MacBook Pros will no longer be available in the stores. While Apple has updated the MacBook Pro with “next generation processors, graphics, and Thunderbolt I/O Technology,” MobileMe will only be available online. You can’t simply log on and purchase MobileMe, though. It looks like you must sign up for a 60-day free trial and then decide to pay later on.
It would probably be a bad idea to sign up for or purchase MobileMe right now as the service appears to be in transition. When iOS 4.2 was launched, iPhone/Pod/Pad owners gained the ability to sign up for a free MobileMe account using their Apple ID in order to use the Find My iPhone (or iPod, or iPad) service.
Now, with the retail packaging being removed from the stores, there is no telling what is coming. There is also speculation that MobileMe is due for a complete overhaul and this could be the beginning.
