I just got the OTA update of Android 2.1 and was snooping around to see if I noticed any "undocumented" additions. Just noticed that there is now a "Dock" setting under the main phone settings. Has that always been there? I don't have the dock, so I don't know what the options may be.
I don't know if we'll ever know why Google didn't support multitouch in the states. I'm betting it had something to do with trying to stay on good terms with Apple. I bet tensions may be rising between the two, or Apple felt that they didn't need the multitouch edge to stay competitive any more.
