I'm not sure why Microsoft doesn't put it up on the App Store. They will probably get a lot less customer information, but things would be so convenient. Apple will stand to make a cut, but then there are several companies which sell both on the web as well as the App Store - why not do that.

Adobe was hesitant at first too. They brought several smaller apps to the App Store at first, then followed by some big ones.

Apple getting a cut is the reason why MS doesn't put it on that service. There's no point in paying 30% if you don't have to, and MS doesn't have to.
