Apple's MobileMe is monumentally uninteresting -- less useful than .Mac.
Actually, it's worse than that. It's inferior to Google Apps, but since MobileMe is an Apple revenue stream they're incented to discourage Google Apps.
This is unfortunate, because if Apple made some modest changes to OS X 10.5 and MobileMe I'd buy a family package of both.
I want a remote system control option built into MobileMe. In particular I want to have full control of my mother's Mac Mini at all times -- without requiring her to do anything. (See also.)
Apple has all the pieces for this to work; even their toy VNC based remote control would be suffice.
[I first drafted this for .Mac in 2005. Found it while doing some cleanup; it's still true today.]
