It is our policy to add sections for all available phones here at Android.net - but we also realize that some members would be happier on a website dedicated entirely to one particular device. On some more popular devices we are able to accomodate this. I believe the Motorola Atrix will be one of those very popular devices with a good community following.
So with that, I'd like to announce that we do have a sister site dedicated entirely to the Motorola Atrix up at Motorola Atrix Forum
Be sure to visit and register if you are interested in the Motorola Atrix 4G.
