I haven't had any trouble to speak of with .Mac/MobileMe.
I use it for backup using Sync from my iMac and MacBook.
I maintain a user group website on the group's iDisk, using the Finder to copy updated html files and PDF newsletters to it.
For my own website, I use iWeb to maintain it on my own MobileMe account, as well as uploading lots of photos from iPhoto to gallery.me.com.
I don't use MobileMe for my primary e-mail, though I do have Gmail configured to grab any of my mail that ends up there (primarily from Apple).

Apple is out of its depth with cloud computing. They never got dotmac to work correctly before moving on to MobileMe. It's been nothing but failure followed by failure.

Mobile Me - where do I begin?
It's incredibly slow, the applications drop connections, going to the Account Management screen usually takes multiple attempts, and this was all just this week.
I would have thought it would have been worked out by now, but the web apps are just not reliable.

This MacWorld article reports minor fixes to a very flawed system. Almost all the problems Walt Mossberg described in July remain and those are the problems that must be fixed for MobileMe to become a viable program for business and busy personal users.
So far it's been a waste of money for me.

GHz Power PC G4 version 10.5.5 ADDRESS BOOK IN A CLOUD I've had my Mac for years. I've had MobileMe since Nov 2007 but never used it until I bought my iphone this week. The address book synced from mac with mobileme once (I don't know when). I can not NOW sync Mac address book with mobileme. I've changed password, empty cache, closed mobileMe, restarted computer and worked on the problem for several hours. Where do I go from here?

In the past, I have directed people to the MobileMe system preference, Sync tab, Advanced button. Unregister and re-register your computer, turn Automatic Sync back on in the MobileMe Sync tab, and click Sync Now. See if that does something for you.
