As a former TMO employee, it was always difficult to get people to even consider the HD7 or Radar. They always gravitated to the slew of Android phones going "oooooo......awwwwe" when looking at screen size, super amoled screens, specs, etc.
I will admit that I am not biased toward any OS. I jumped on board with Android when the G1 first came out and over the years have played with Android, Blackberry, Symbian and older Windows phones.
On my home office desk, there sits a Nokia Astound, G1, BlackBerry 9700 and 9780, HD2 and Im currently toggling back and forth between my HTC Amaze and Radar.
I will say this for sure....that my Radar is soooo much smoother than my Amaze and my Amaze is rooted. As I tinker back and forth, the Radar/WP7 is becoming my choice of OS.
I do miss my Google Navigation (WP7 not as good), and custom text apps and notifications but I'm slowly getting over that for the smoothness and consistency of WP7.
Sorry for the long post.
Just wanted you to know that as a current Android and WP7 user, I totally agree with you.
