Windows Phone 7

I've been trying to get a handle on the WP7 OS, I have yet to see a developers review of the system. There are lots of C# developers excited to have a mobile outlet for their talents, but no one publishing a critical comparison of the OS and it's development environment.

At best I've seen a handful of tweets pointing out what one would expect from MicroSoft - a heavy, monolithic OS that handicaps users and developers. The biggest red flag is that the framework only allows communication on port 80, eliminating WP7 as an Internet aware device in any meaningful sense.
