I think WP7 + Nokia is a great move. Nokia makes great hardware and Microsoft makes great software and has a HUGE developer base.
I have switched from iPhone to WP7 after 3+ years and I am really happy with it. I do miss some of the apps and games but love other features that make up for it.
Hate Microsoft all you want but they have made great software (and also bad).
Nokia + MS can give a good fight to others provided they work very closely and act in lightning speed ... but this should be plan B and not plan A.
Also Nokia is HUGE everywhere (except north america). What they have to do is to spend more on ecosystem to get things done as fast as possible and also spend on marketing in north-america ...
MEEGO is a universal OS, it is used in cars, TVs, Games, tablets etc. so it's better to make it part of Plan A where users can be switched flawlessly from symbian with a solid ecosystem in place.

Great = win7, wp7, zune, visual studio, expression suite, office suite, sql server.
Bad = well you all know the list: IE8,7,6,5,etc..., hotmail, windows me and a ton of others that I am too lazy to list.
If history is any indication, Microsoft will eventually dominate the mobile marketplace or at least be a very close second.
