Should Nokia drop Microsoft?

The Reviews are in for the Lumia 900 and while they are highly complimentary about the hardware (even John Gruber gives it an A), Windows Phone 7 continues not to impress. Microsoft needs Nokia in a very bad way. The other handset manufacturers aren't interested in WP7. They can sell a lot more Android phones, a lot more. Nokia doesn't need Microsoft. Like the others they could sell far more handsets by going to Android.
