Um... ever heard of DirectX?
Piss poor GPUs for your buck, no attempt to actively coax game engines to the Mac (Havoc could have been bought, Apple didn't bother, responsible over the last 5 years for a large number of AAAs never coming to the Mac) etc - Apple have done almost nothing with OS X besides the Intel transition to encourage gaming on the Mac at all. Steve has long considered gaming a waste of time, until he realised on the App Store that give people the option and they will game in vast numbers on Apple products.
Hmm, hadn't look at it that way. Your post makes sense and is quite correct on this respect. Sorry, I thought your earlier post was just a jab at Apple for no reason. Gotcha and I agree.
