easy enough to use for me (I'm a linux newb) and I can setup steam on it!
edit: forgot to mention I can get hibernation working on Ubuntu when I couldn't figure out how to do that in Fedora
Are you playing steam games that have Linux versions? Or is the "comparability mode" stable and fast enough that you don't really have to think about it?
Because it just works. Because it's based on free Debian and not corporate RedHat. Because mainstream Linux needs a flagship distro and that distro needs to be used and supported.
