You clearly don't know http://news.ycombinator.com/user?id=jacquesm very well. He is not at all resistant to change. To the contrary he understands tech better that most of us can ever dream of.
Microsoft has been trying to figure out how to create a decent phone, and has been failing. There is no reason to believe that Microsoft's team has addressed the causes of their past failures, and therefore there is no reason to believe that they will suddenly, miraculously, start succeeding now. Theoretically Nokia can tell Microsoft how to do things better, there is a lot of expertise there. But there is every reason to believe that a lot of that institutional knowledge is about to be laid off. For better or worse, Nokia is now dependent upon a team with a history of failure.
I know you believe differently. You expect Android to take the role of feature-phones now, while MS and Apple control and split the high-end market. So I'll offer you a bet. In 2010 Nokia is estimated to have held 33.1% of the phone market. I'll bet you $100 that by 2015 either Nokia and Microsoft have parted ways, or else Nokia will hold under 15% of the phone market.
Care to take that bet?
