Okay, I RTFM and I have to say it is as useful as a football bat. Using the Lapdock to post this. I keep rubbing the track pad and unintentionally repositioning my writing spot. Frustrating! The more I use this thing the less I like it. It lacks the touch screen of a tablet and the power of a laptop. While I don't want to have to pay $20 to use the MAXX as a hotspot, I don't see the need to do it that often. When I will need to use it as a hot spot chances are my wife or anyone else I am traveling with would benefit from the hotspot too.
Looks like the Lapdock is not ready for prime time (IMO).
