In what way?!?! The consoles have local multiplay, better graphics, can play media like DVD, bluray etc and of course, can be put onto a 42"+ TV.
A handheld does none of that.
If a new fiesta comes out with new features, it will sell, just as if a new BMW 5 series comes out with new features. You are comparing a micra to an Aston Martin, and farmville to CoD. Stop it; it's absurd.
The primary way in which they compare is the type of electronic gaming they provide: that is far more relevant than anything you listed. And, in the Wii's case, it was the Wiimote and the rather revolutionary games Nintendo made as opposed to what you listed. I'd argue, indeed, that it is primarily software that drives sales (especially in Nintendo's case), which, is what both handhelds and consoles have, of course. So, to argue that which bolstered a handheld's sales (software, price point, etc) could not possibly do so for a home console is unwarrented, I would say.
To lavish praise upon this title, the assumption of a common plateau between player and game must be made. I won't open my unworthy mouth.
