Apple ID and MobileMe ID
I have an Apple ID that was set up when I first purchased my MacBook Pro and it's the same one I use for iTunes. After MobileMe was released, I set up a MobileMe account, within which the ID was set up by creating an @me.com address and password thus creating the MobileMe ID.
Do I set up iCloud with the MobileMe ID so that Mail, Contacts, Address, photo streaming, etc. are synced through iCloud or do I set it up with my main Apple ID that's associated with iTunes? I know you can do that, but if I set up iCloud with MobileMe, does that prevent iTunes music match and syncing of iTunes purchases from occuring in iCloud or do I have to set up iTunes as an additional iCloud account? If I set up iCloud with the Apple ID associated with iTunes how does that effect my current @me.com email and MobileMe account?
