I just want to echo this to make sure that everyone understands Google and Microsoft are worlds apart on support.
We've all heard about the horror stories that it doesn't matter what you do with Google you cannot get human support unless you get to the top of HN or Reddit.
MS are totally different, they offer support for every service, you just have to pay for it. I think they also offer different levels of support, some of our programmers at a previous (small) company could talk to the Silverlight team over problems they were having after it just came out.
Funnily enough, when I google "google paid support" the top result is this little (frightening) gem:
http://support.google.com/accounts/bin/answer.py?hl=en&a...
Compare that to this, "microsoft paid support":
http://support.microsoft.com/gp/services/en-id
I'm in no way affiliated with MS, actually use Google Apps myself.
