This is the "toner-head" argument that Steve Jobs railed against as the reason that Xerox never successfully marketed a GUI based machine.
The toner-head argument is basically that decisions are being made by sales and financial teams who don't understand what they are selling.
I'm making multiple arguments here, but none are the toner-head argument:
Argument 1: iOS is a better platform to move into gaming on.
Argument 2: The compromises needed to make Macs good gaming machines are completely different to the direction Apple thinks is good for the Mac.
Argument 3: Apple has never cared about gaming.
Really, this is a very long and complex discussion, but I just wanted to point out that Argument 3 was not really accurate.
Other than Prince of Persian, I don't remember a single one.
Then again, in Portugal outside the university campus there were no Macs to be seen.
Yet we had Amigas, Ataris and PC everywhere.
