If VALVE really manages to convince lots of their 'partners' to support Linux, this will be a big win for us.
Maybe this is something we should even more look forward to than 'just' having the VALVE catalogue ported to Linux.
Then again, what I don't get is why VALVE hasn't managed to convince those partners to port their games to Mac OS?
What can be VALVEs strong arguments to make them support Linux while most didn't with Mac OS? (If it is not a 'SteamBox')
AFAIK only a tiny fraction of all Steam titles are available on Mac OS.
