I have developed for Android, and recently started developing WP7. So far, I prefer the development environment and tools for WP7. Silverlight + Blend studio allows for quick and beautiful apps, and XNA studio does much of the work necessary to get the frame updating and rendering working. So far I am impressed with WP7.

I don't think enough people bring up the advantage Expression Blend brings to the table. It's like being able to design your UI in Photoshop

(Say what you will about Microsoft the one thing you have to give them credit for is the amount of money they spend to create developer tools)

Things might change once Adobe gets Flash up to speed on Android but until then Blend is by far the most powerful UI environment available for any mobile device.

Yes, most people don't even know that Expression Blend exists. The first time I used it to customize my UI in Silverlight, I was blown away how quick and painless it was. To simply change the look of a button in Android, I had to spend far too long creating .9png files or w/e they are called.

Yes, so please don't do that. No user wants an app that looks different from every other app on the platform.
