Very true, hence the reason why I never used it on my TF101. I'm just saying it would be even worse Android is meant for small screens, "normal" Linux distros are meant for normal laptop screens and desktops, also the biggest difference that separates the two are the interfacing options: Android is meant to use a touch interface, whereas Ubuntu and "normal" Linux distros are mean for a mouse and keyboard. I used to use Ubuntu on my Asus eeePC 1005HA before I got my TF101 and it was still a pain in the ass.
I can't seem to install ubuntu on my Nexus 7, I'm using the app from the market. When I try to install it just says root access required to run this script. I have rooted my nexus with Super User installed and working.
