I'm super excited for iCloud but I'm still wondering what the hell I'm going to do with my two separate Apple ID accounts: my original one, which I made to buy stuff on iTunes—and still use to buy apps—and then the MobileMe account that Apple forced you to make as a separate Apple ID.
I just want it all to work together, dammit, especially since I paid Apple money for all this stuff before they decided to make it free. One account, all my info, all my apps. Just give us a heads up. I think my annual fee bought that much, since sometimes I feel like it didn't buy that much else.
