Well, iCloud remains to be proven as a true alternative. Keep in mind, apps COULD in theory already be offering free sync over MobileMe, but guess what? It sucks.
Perhaps Apple is doubling-down here. They do seem to be lauding their infrastructure and making it free doesn't hurt. Still, we have yet a while to wait and see if iCloud pans out. Having bet on .Mac and MobileMe, excuse me but I'll check this round.
Edit: Wow, too many betting analogies.
