Being that the company Iwork for is starting to sell android tablets, I am very interested in this my self. The one I have on my desk right now runs
Firmware 1.6
Kernel Version 2.6.39-00236-g4f8dbbb-dirty
Build Number 1.7.3
Our new tablets are supposed to have 2.1( I Think) and run at 800 mhz.
With this one I cannot download apps and hate the fact that it is setup to run on a phone. It has the WM8505 processor on this one.
its not all the os its more that the tablets need to be made to work with android better, so i dont think google will make a special os just for tablets but they might create tools so devs can tweek it to work with tablets better.
