You said, "Interchangeable phone cradle: As I noted above, the Atrix and Bionic Lapdocks have connectors that are specifically designed for their respective phones. You can???t connect a Bionic to an Atrix Lapdock. But other than their phone cradles, the Lapdocks appear to be identical. I haven???t cracked open the Atrix Lapdock, but I wouldn???t be surprised if Bionic version was an exact copy with a different phone cradle."

So go ahead and interchange them (the phone connectors; I presume they are the same on the Lapdock side) to see how far they have carried the interchangeability. And then report on that (underline 'that'.)

Thank you.
