I think you conclusion is right but the way you get there isn't quite. It's not so much about some special property of Android or Meego, it's about control. WP7

I think you conclusion is right but the way you get there isn't quite. It's not so much about some special property of Android or Meego, it's about control. WP7 might work great on tablets but Nokia can't just decide to make it run on tablets. That's Microsoft's decision. Nokia doesn't control their destiny. If they settle on WP7 the best case scenario for them is to become a company like HTC only with even less control over their software.
