ubuntu for android

Thinking about finally getting into the world of the tablet, I am faced with the decision of what OS?
Quickly ..

mac - no

windows - no

android - seems like the best, but there's all that google garbage. And God only knows why they have to know where you are by what wallpaper you decide on. Yes, there is geo loc on the wallpapers, I hate that shit, and it'll only get worse.

still, android it is then. I don't like macs and windows is largely untested on the tablet and is too expensive anyway.
Then I find out about ubuntu on the android and instructions about installation on the nexus ...

multi rom .. boot android or ubuntu

job done.
