I'm also using a Galaxy Nexus beside some iOS devices, and I can't see what you are seeing - Windows Phone is plain anti-polish to me. Smooth animations, a good typeface, and exaggerated visual hierarchy are all there is to it. UI widgets developers can choose from are also very sparse - they are good for CRUD apps with low information density, but that's about it. I currently develop & design for iOS and Android, and I don't think I would want to do that for WP7. I hope WP8 has more polish, widgets-wise.
