People always seem to forget that Sony did almost everything the switch is doing now, way back in 2011.
Along with other innovations such as custom key board & back touch screen.
Sony gets almost no love for championing the addition of Cross/Play & Cross/Buy thats available on the Vita.
The switch is a good game console don't get me wrong, but the mobile home game console feature has been done long before on the Ps Vita.

And even before that :

Sega Nomad (1995)

PC Engine GT / LT (1991)
