In my latest blogpost, I mention Arch Linux ARM as favorite OS choice for all tested boards.
Hope you'll lik the quick comparison, I usually post about programming and nothing else
For what is worth it, I've tested Fedora, Lubuntu, picuntu, Whateverbuntu and still I rather learn and like the power of ArchLinux even if from time to time I might have bigger problems with some extreme change via pacman update
Thanks guys!
