But it's portable.
Though if you don't mind the input lag and image degradation you can stream console games to your portable PC, I guess, with mobile hot spotting... though it'd be terrible.
Nintendo feels they have no choice but to purse gimmicks. The Gamecube was more powerful than the PS2 and consistently cheaper than both the PS2 and Xbox and did not sell well. I think graphics + gimmicks would be better, but they don't apparently.
But personally, I'd prefer Nintendo go third party. Release their big games for PC + Playstation + Xbox. As for portable, they can make a deal with Nvidia to release versions of their games on Shield if they think it can sell enough copies to recover development cost. New Pokemon for PC + PS4 + Xbone, and buy a Shield if you want portability. Nvidia wouldn't complain.
Sega quality of games suffered after the Dreamcast died, but that doesn't make it inevitable.
