Previously I had a MobileMe account for synchronising my settings between my devices. Today I transferred this MobileMe to iCloud and got the free 20GB storage upgrade. In iTunes, App Store etc. I have been using my Apple ID (my gmail) for a long time. Since I'm not using my MobileMe Mail I think that there is no longer any reason for using this account? Therefore I chose to use my Apple ID for my iCloud in iOS5. But in Lion I have an option to create a @Me.com email, for my Apple ID. Can I transfer my old MobileMe account email for the Mail in the Apple ID instead of creating a brand new Me-address? Are there any other reasons for using my old MobileMe adresse as login for iCloud on my devices instead of my Apple ID? I just think it would be confusing using different logins for iCloud, Store etc.
