Everything looks and works great. The drag & drop for calendars does as it should. Mail features are nice like the Quick Reply. Haven't really delved into the Web Gallery to see how it does but my pictures are there from the previous set up.
It would seem that my syncs are still working because changes I made to Address Book contacts since the .Mac blackout are showing up in MobileMe; likewise with iCal events. Still, I don't have the MobileMe package showing up on my Mac for installing and of course, there is no iPhone 2.0 upgrade either to get that aspect going on my iPhone 2G.
Still, I do now have access to MobileMe here in little ol' South Carolina!
