I like the OS, totally dislike the stock browser. I'm waiting on Firefox 4 Beta to be announced for it - just like it has been announced on Android & Maemo 5.

To be honest, I dislike the Android stock browser too, use Dolphin HD instead.

MicroB is still "tops" at the moment in my book. But WP7 seems to get more right than wrong - that's something I thought I'd never say.
