I have bought one of these and installed a custom Firmware which gives access to the official Android market.
Great tablet, capacitive screen, powerful processor. Great battery life.

Have a look at the forum that is in the link for loads of information and I am happy to give you any advise
I have not heard of anybody attempting to port Windows 8 onto this tablet though would be great as I am using windows 8 preview on my laptop
