mmm maybe just online steam apps for ipad games or so....apple pc's arent for gaming. Would be cool dho, the more the marrier.
Can be interesting, but I'd have to see it before I believe it. I generally hate Apple for all those "Now the new gen device from us taht is barely different from last month's version, but is now even more expensive!" But they also are inventing (or re-inventing) stuff that can be pretty cool. So perhaps with the best of Valve and Apple combined, there could be the most awesome thing ever...
A shiny brushed aluminium Valve/Apple PC/console would be cool but I think that's just going to be dream and it probably will be something iPad gaming oriented or just two big companies talking like so many do.
Apple and Valve have a long way to go in gaming on apple. ppl still have a lot of problems with steam on mac, and often those bugs need to be fixed in a next release of steam client, and games on a apple are (of what I hear) a nightmare with FPS, lag, hitreg etc.
