I love consoles, but no.
Consoles are already bad enough when it comes to price vs. latest tech. You're often getting inferior parts, bundled together, and sold at a price that is not market friendly for the consumer or producer just because that enables the massive revenue from software, digital marketplace, and peripheral sales.
But then APPLE getting into the mix of things? They are known for selling inferior products, with jacked up prices, just because of their name and a monopoly they hold on college software markets. From a technical standpoint, they sell trashy hardware, with simple software, for a price that would make anyone who knew what they were doing vomit in rage. And they want to bring that to the console platform?
Consoles exist so people can play games cheaply. Console gaming is, in every sence, inferior to PC gaming. I suspect people will flame without applying critical thinking skills, but it is. There is nothing your Xbox can do that my PC can't do, and better. BUT THATS NOT A BAD THING. To get a PC running well, you need to invest a lot of time, a lot of money, and put up with a lot of extra crap that can come from the thousands of variations of rigs. Consoles eliminate that, and allow gamers to enjoy games on a much leaner budget. How would Apple fit into this business model?
They don't sell any of their products cheap. Their biggest export is their name - thats what your paying for. If you had to pay an extravegent ammount of money for a console, from a company that is known to rehash existing products every year (iPhone 4S. Cough.), why sink the money into it? If its not cheap enough, it doesn't warrant my purchase of a console because consoles are the poor mans way of gaming. If its too expensive, why waste my money on a product that rivals my far superior PC in price, but can't hold a candle upto its performance. Entering the market would require Apple to COMPLETELY revamp their business model, their demographics, etc.
NOT TO MENTION, THEY HAVE A GAME SYSTEM. THE APP STORE. And while you do get gems in it from time to time, its mostly cluttered with crap thats meant as a time sink. Apples knowledge of the market is skewed by the indie and garage developers who make a killing on the App Store, by participating in some nasty practices. How many App Store games sell power directly? Is that something you want made mainstream?
Anything above the casual crowd, they'll drown. Make it too expensive, you alienate the core demographic for console goers while turning off PC gamers because the Price to Power margin. It doesnt make sence for them to get involved.
