I disagree that they are less cumbersome. They are far and away bigger than most portable gaming devices of the past, and lack the built in protection most of them had by being either snap shut-able or simply a brick. Meaning you not only are carrying a noticeable, large device that is obviously expensive but you also have to get an even bulkier case for it. You can't just slip it in your pocket like most of the older, popular portable systems.

I don't think Nintendo is ever going to be in trouble, they have way too much power to just print money for that. My worry is that they themselves will cancel and muck with franchises in response to emulation and other problems.
