I got the HTC Inspire a week ago, but was thinking about switching to the Atrix when it came out. Today I had the first chance to compare the screen size. There is just no comparison. The Atrix screen was much smaller than I thought, even though it claims a 4" screen, it was about the same width as the iPhone 3GS, only longer. Side by side the Inspire 4.3" screen looked huge. I wasn't able to see the Atrix screen in action though.
Having learned ATT will force me to upgrade to the tether plan if I used the HD dock, I am giving up on the Atrix. The only thing missing on the Inspire that I want is the HDMI output to HDTV. HTC supposed to have the Media Link kit out already, anyone heard anything?
BTW this Inspire is my first venture into Android, so far impressed.
