MobileMe Sucks!
This service is a disgrace for Apple.
Dropbox, gmail, googledocs, etc are all free and work 1000 times better than MobileMe.
If Apple hired some decent engineers who knew how to design a cloud based service then they could lead the way. Instead Apple throws out a poor performing, poorly designed piece of c#*p and charges for it.
The mobile computing world is crying out for a great cloud based service to store digital data such as, music, movies, word docs, pdfs, powerpoint files, applications, photos, and various app docs. That way you could always have your media and data backed up, yet easily accessible.
I can't even used idisk for files larger than 50MB. It is so S---L-----O-----------W and never finishes. I can use Dropbox on files up to 2GB for free and it works amazingly fast and seamlessly.
The Itunes desktop application is now bloated, slow, clumsy, and has turned into a jack-of-all-trades application that doesn't do anything great anymore.
If Apple made a great cloud based site, then itunes could be eliminated and all purchases could be stored online and streamed or downloaded directly to your chosen Apple mobile device, ipod, ipad, iphone, or laptop.
Please Apple, stand up and deliver. MobileMe is a FRIGIN JOKE!
