Obviously, I'd want high power, low price, high portability 
But, past a certain point that allows for easy reception of PS4 downports, power is the least concern among those three. Get it to $300, $250, and then $200 (possibly with new SKU) fairly quickly and let it have decent battery life. Switch should first be a well priced portable and then a console that can play at least lower end PS4 games.
