Re: @ Mark Jan
Thanks for your reply. I fully understand one of the points you're making here. MS have their own best interests at heart (a black heart admittedly...) and not Nokia's. And it may well be that Nokia have picked the wrong technology, and should have gone with Android. Or possibly, both. Be the market leader in Windows phones (and best pals with MS), and knock out some me-too Android ones, so you're at least getting some sales from those, and not disappearing out of the market.
I suspect if they'd gone that route, they wouldn't be getting $1 billion marketing support our of MS - and given their current position, $1bn is quite a lot. If they go the Android route, and can only make $10 profit per phone, then they'd have to sell 100 million Android handsets to be worth it!
What I still don't get, is when you said this:
Nokia has everything to lose and Microsoft everything to gain.
That doesn't look like straight talking common sense to me, but MS hate.
In this case MS and Nokia's interests are aligned. If Win Mob 7/8 fails, then MS are stuck with just XBox and the Corporate desktop/server market. And they will be sad, because that puts them in a mature market with low growth (nice profits though) - but not sexy. So they want it to succeed. They aren't trying to kill Nokia and buy it cheap, as some people keep trotting out. That's just silly. Obviously Nokia risk going bust - but moving to Android isn't that much less risk, as the competition is much fiercer, hence lower profits.
