I'm a linux user... I use opensuse 11.1 (w/ kde4). I was a big pclinuxos guy, but their releases are tooo sloooowwww (I like my OS like I like my roms, the latest and greatest/unstable
)
On my dvr I use mythbuntu (ubuntu), I'm usually not an ubuntu guy but for server/dvr/stuff like that I use ubuntu b/c the guides are so good.
