I think they didn't go with Android because they were terrified of becoming "just another android maker" in what is already a fairly bewildering device market. WP7 is just gestating and they are the only device maker that now has the right to customize it so they actually have a bit of room to differentiate themselves or so the logic goes. I don't claim to know whether this is ultimately a good decision.

I still get amused when people call Elop a "Trojan" as if he somehow snuck in and took over the company without anyone noticing. I mean, think what you want about the MS deal, but the reality is that the board installed him to do something exactly like this. At the request of major shareholders who were tired of watching their investment disintegrate under current Nokia direction. That "shareholder revolution" we heard about? It was a hoax. That was one bored random dude with no investment in Nokia at all. Wake up people, the shareholder's aren't going to revolt and remove Elop. Installing Elop WAS the shareholder revolution.
