Right, some people here are open SW enthusiasts, and also not friends of Microsoft. But I don't believe this hits the point.
I also own a Window Mobile device that I also like.
The MS deal itself, as said before by others also, is not a problem, the problem is its exclusiveness and as it seems lack of risk management.
AGAIN: Leading a company is NOT GAMBLING.
Let's wait 2 years and hope that Nokia management has also done its job concerning risk management.
