Exactly. I dumped .Mac for Dropbox and Gmail. Both work better that MobileMe ever did, and both are free.
I had MobileMe for around 2 months but then I questioned why I was shelling out AUS$100 or so dollars for a service that I really didn't and couldn't take full advantage of (I have metred internet so the remote storage wasn't used much nor the 'back to Mac' which left the email service which wasn't anything to write home about). So I closed it off, got a refund and went to Microsoft's Live services; they integrate well with my WP7 device, I can upload documents etc. to my skydrive using 'Microsoft Document Connection' etc.
To be totally honest what Apple need to do is provide 'MobileMe' free of charge and charge extra for some premium service because quite honestly I don't see the benefit of using MobileMe over the free services that exist out there in the various forms.
