While in class today I asked a number of friends who have Macs if they tried Steam for Mac yet. Everyone of them who said they have Steam said they can't launch Portal(currently the only ported game) due to problems with Steam. My current theory as why Valve has announced or released anything Linux related is because they can't handle the additional Mac users, they need to wait for the server load to die down.
Strange, Portal on my Mac (well, not mine, but that does not matter ) works well I got it for free, you know, anniversary
it wasn't about stating it wouldn't come to linux (at least for me, go read all my past posts on this), it was how it was handled by phoronix, really really badly.
