Apple's problem is that they put "Looks" before performance.
They crippled their chances of ever becoming a serious competitor to the PC for games due to deciding to use giant laptops on a stand which meant they could not cool any decent graphics cards, handing the gaming crown to the PC for years on a plate.
As for the future who knows.
And today they are the Gold Standard for consumer tech.
OS X runs very well on Apple hardware. OS X apps run very well on Apple hardware. Not sure what the problem with performance is.
Those "laptops on a stand" are selling in record numbers while the rest of the computer industry is in a sharp downturn.
They've got the future of gaming all locked up nice and tight on iOS, not on PCs as we know them but on mobile devices which keep getting more powerful and which as we know, are the future of computing.
Your anecdotal opinion is cool and all, but perspective please!
Apple has been completely and unequivocally unaffected by conceding the gaming market to someone else. Instead, they've revisited it and have created a new standard. if that's what "losing" means then I'm damned impressed.
