Considering the potential value of Valve in the future I couldn't imagine what that price tag would be. If I owned Valve I would tell Apple they didn't have enough money, even with all that cash on hand. Valve almost always makes serious money with their games and Steam is practically software written for printing money. I also think that Apple's culture would clash big time with Valve's culture causing major issues. I think you are wrong about Valve and the quality of their software. You are basing this on one piece of software that is essentially in eternal development (as you point out) and then basing it all on your own personal experience. Even your first example is most likely an issue with TF2 and has nothing to do with Steam. At least you mention that Portal 2 is fine, but you're ignoring every other game Valve has ever made and/or been involved with. If your only problem with Valve's software is TF2 then I would have to say they have an excellent track record. I say Valve has mastered the ability to deliver quality software.
