I tried and it's amazing

First I rooted my TF to have the custom clockrecovery, then I flashed ubuntu and prime 1.7.
Everything works perfectly, but Gnome is quite slow so I changed my Desktop manager (tried openbox and fluxbox, same performances).
Using the TF with a mouse and ubuntu make me think it is
really a notebook

I can compile some C code with GCC, read PDF, browse internet with Firefox ... \o/
Bad points are :
You need an USB mouse because touchpad doesn't work.
You need to have some linux skill (just a little)
Connecting wifi is quite a challenge (but I did it)
I followed this tutorial :
