Mountain Lion Notes Sync

I just got Mountain Lion installed this afternoon (thanks to the Up-to-Date program taking a few days to send out my code), and syncing notes using iCloud seems to be broken. I'm logged into my iCloud account, and I can see things from my calendar and Reminders, but when I try to sync notes, I'm asked to choose an @me.com email address to use with iCloud. Does the Mountain Lion Notes app not sync using my normal Apple ID the same way the iOS one does?

Any help would be appreciated.
