Not so fast...
So is DropBox...and SugarSync. The difference is that they are much faster and spread around better datacenters

I really don't get why people pay for MobileMe...its a complete failure as a service. It doesn't even come close to GMail when it comes to performance.
I sense its only being purchased because of a certain fruit sitting in the corner of the screen.
Actually, MobileMe allowed me to backup email going back to 2004 that was in my Apple Mail app. I had to always back up my email databases. Now with MobileMe, I've uploaded all of that email to the cloud and when any new email comes in, it goes to the email in the cloud. MobileMe is way powerful when you don't want to use Microsoft Exchange/Entourage and you have your own domain.
While Gmail can handle up to 5 unique domain email address, GMail is horrible in Apple Mail and the iPhone. Gmail in Apple Mail doesn't like the Rules I set for email to go to certain folders.
The reality is, minus apps folder and documents folders, my laptop could get stolen, but thanks to MobileMe, everything else is backed up—backups of all my email going back over 5 years, calendars, contacts, bookmarks, keychains, my dock, my widgets, notes and OSX preferences.
While my laptop has never been stolen, I recently had to leave it with Apple for repairs for a week. I am a business owner and the moment I got home, I loaded up my aging Mac Mini, added my design software, and was able to keep working on my design work like nothing had changed (albeit, on a slower machine).
It' not about getting a Me.com account (And I agree—if it were just email, it should probably be free.) I do have a Gmail account and know that Google's service has definitely crapped out on me as well. In fact, I don't even use my Me.com email at all—it's about the peace of mind that my laptop, iPhone and iPad could all break, get lost or stolen (heck, my house could burn down), and yet everything is backed up, ready to go as soon as I replace the device.
