Seems awesome, but I'm afraid the screens too big to fit in my pocket :'(. Oh well, maybe the 3DS line is sticking around for a little while since the Switch seems to be marketed as a home console mainly.
This trailer really does a great job of showing the "Continuum" inspired usefulness. Can we talk about how people were playing mario kart with only one "half" of the controller??
I'm probably going to head over to the ARS reveal thread.
