The PS3 runs Yellowdog.
The media PC (and my other PCs) are on 14Karat Linux

(my personal variant of Fedora 10 currently.)
I have used Ubuntu (and other Debs), Mandrake, Mandriva, SUSE, Knoppix, Slackware, Gentoo, Linspire, Freespire... and some others I can't recall currently.
Settled down with Fedora and made it do everything I need it to. Dropped my XP partitions and never looked back.
Not sure what the "you're not missing much" comment about Fedora was earlier - I guess I don't know what I'm missing.
I've been running various Linux distros since the late 90's. Aside from a few driver issues here and there, I think they are all equivalent - just depends on what you want them to do.
For a Windows user coming to Linux, they don't see Linux... they see X in whichever environment that was chosen...so, Gnome or KDE (or the few other lesser knowns out there.)
For some, Linux has too many choices and they don't like that... but that's what I do like about it...
The media PC is a 4-core AMD Phenom. 8GB RAM. Twin 1T SATA drives (hoping to expand to 4 drives & RAID 5.)
Dual Head NVidia. Dual OTA Tuners. Twin dual-layer DVD burners.
It just works...
Someone was asking about an XP variant?? Maybe try Darkstar - it was touted to be similar to XP... if it's even still around...
