I stumbled across this forum yesterday while I was searching for a tablet/laptop solution.
Boy am I glad I found this place!
From what I have read here it looks like a Razr MAXX and the Lapdock 500 just may be what I have been searching for. Prior to this I have been leaning towards the ASUS EEE Transformer Prime. The negative points of it are that it is wifi only and costs ~$700 for the tablet and keyboard.
With my Verizon discount it looks like I can get into the razr MAXX and a Lapdock for ~$650 and I get 4G!!
I'll let you all know if (when?) I get the setup and my opinion after I have a chance to use it.
