Same way Microsoft opens up their closes system? Or Sony?
Its not about Open or Close, its about the products and people's preference. iOS type games will cater to casual gamers like the Wii, there's a space for that, but remember how people thought "hardcore gamers won't want to use a phone to play games."
Now you're seeing Nintendo and Sony's handheld gaming devices fading to extinction because there is not enough people buying their handheld units for them to make money.
Sony is comparable to Apple in the sense that they've overreached in the past with closed systems (Beta Max, anyone?). Microsoft might
like to have an Apple-esque propriety eco-system (and they're arguably reaching for it with Windows 8 and their App store), but Microsoft is watched far more carefully because it owns so much of the OS market.
What bugs me about Apple's insistence on proprietary eco-systems -- and they've done it forever; it's only in the last decade or so that Apple's achieved major success with that model) -- what bugs me is the presumption in the culture that Apple is the hipper, nice-guy alternative to the big bad corporate IBM/Microsoft machine. Pernicious marketing at its finest: Apple is every bit as greedy and grasping as any other corporation, and as a practical matter Apple is often significantly worse.
In any case, say what you will about the ubiquity of Windows in the desktop PC marketplace; Windows is an open ecosystem, at least as of this moment. You can run Windows on basically any hardware, and you can run basically any program on Windows. That's why it's always kicked the crap out of Apple's OS, no matter what cutesy UI advantages Apple could tout at any given time.
You're right that tablets and phones are squeezing the handheld console out of existence, but that's only natural: the tablet and the smart phone offer essentially everything a handheld console ever did, and they offer a lot more besides. It remains to be seen whether Apple can offer a competitive product in the console market. Hell, whether Apple maintains its primacy in the
tablet market remains to be seen.
