The early Nail in the coffin for Mobile Me. just wait till there mobile storage comes out then there really is no point to mobile me.
I have a feeling that once google gets push email out for this (if they do, hopefully), people will start migrating en masse away from MobileMe - you can already replace it with free services for the most part, such as google mail/contacts/calendar, dropbox for files (2 Gb limit though, but it works perfectly) and Flickr for photo sharing. I personally use JungleDisk for backup, though that is less than free. Flickr also works great for photo sharing.
And, on the plus side with google, you can use your own domain name (a huge reason why I don't use mobileme - I can't migrate the whole family domain onto it and don't want to set up forwarding for various reasons).
