MobileMe Problems Show Apple Needs an Infrastructure Lesson
My unspoken suspicion was that Apple really just doesn't have much experience with building Web applications. Yes, they have the Store and their main website, but these don't really have very much interactivity and the infrastructure required would be completely different from the MobileMe apps.
The linked article is from Chuq Von Rospach, who has an insider's perspective on things there. He says that Apple is already very capable of running MobileMe. The fault was that the team (apparently) flew the "we're ready" flag when they clearly were not.
