I think the general positive attitude towards WP from Engadget and Gizmodo are both very telling of how good the OS is going to be.
Agreed. I've had my WP7 phone for 6 months now and i love it more than ever. They really have something here. It has the fastest growing App Store and the Live tiles feature is new and innovative. So much better than static icons. They just need some new phones, which i would expect in the next few months.
