Is Mobileme the same as Icloud?

There is no mobileme service any longer - has not been for well over a year now (mobileme was officially turned off back in July 2012).

If you had mobileme, you should have migrated your account to iCloud long ago. If you did that, then your mobileme email address lives on, but is merely an alias now to the iCloud account email.

iCloud does not include all the same services and features that mobileme did - http://www.apple.com/icloud/ (notably, iCloud has no generic online document storage like iDisc, nor any web hosting liking iWeb).
