Agreed. Imagine having an xb720/ps4 with cross platform access to iOS apps, itunes, along with all the other media functions.
That's compelling.
That's expected.
What's more compelling to busy folks (thanks to broken economy) is I can take the console, or rather media experience, anywhere when I'm too busy to play at home. Or when someone else is using the TV. I game where I want to (e.g., in bed under blanket, at work), or where I can afford to. And I buy the game once and use it on any devices. The games start as cheap as $1 (or free !). That's a more compelling scenario to working folks.
The "touchy" built-in screen + UI is not the only things special about iPad/iPhone. They are not the only things people will copy.
