Just as in the Android application store it's actually up to the individual developers to decide on the price and other attributes of the applications that you see. Microsoft isn't playing a role in the pricing in the majority of what you see.
BTW: Don't confuse Droid for Android. Android is the name of Google's mobile operating system. Droid is the name that Verizon Wireless licensed to brand their Android Eclair (2.0) devices.

It takes all the running you can do to stay in one place.If you want to get somewhere else,you must try to run at least twice as fast as that.
