The difference may be who does the differentiation. I think part of Mokia's problem is their developer talent isn't super strong. Them doing significantly dev on Android is a problem. If MS adds support for Nokia functionality on WP7, Nokia can focus on HW quality and drive requirements for MS to build the SW that exploits it.
From what I can tell the negotiations with Google and Nokia went really poorly.
