So I've been toying with the idea of buying a used Macbook 2,1, flash libreboot and install Trisquel on it.

I know much has been said about GNU/Linux on Apple products, but there are so many different Macbook models and GNU/Linux distros that it's hard to get an accurate picture when searching online.

Basically I was wondering how is the experience like. Does everything work? Is it slow? Any warnings? Words of advice?
