I was using Arch with gnome and the main issue was text size for certain applications, in particular at the time no chrome build, not even dev tip would render text in menus etc. at a non-tiny size (though I could zoom websites and get nice retina graphics)

I've now switched to having a dedicated linux desktop and just letting my mac continue to just be a mac for now. After many hours of effort there's a point where you wonder if it's worth it. I want to contribute to the linux kernel, so feel I should live in linux too, the desktop is my solution to this (if a bit extreme!)

Which offer of help? :) I am really undecided on the systemd thing. I read terrible diatribes against it, but a friend recently pointed me towards an article which contradicts many of these points - http://0pointer.net/blog/projects/the-biggest-myths.html. the reality is it's a lot faster for sure all other concerns aside. I'm glad arch defaults to using it as a user :)
