There is, in fact, a market for such a console. Quite big since what Lite takes away isn't much, since if you just care for the games and the gimmick isn't what you care for, then it's a perfect buy because it has the same specs and better battery life.
I would get it only because I don't really care for any multiplayer game and don't feel compelled enough to get a regular Switch, since all I really care about are the single players games, only outlier being Smash.
Also don't care for TVs normally.
Let us not ignore this thing is a PS Vita but better, the Wii U was wack
All in all, I shall wait before anything, more versions of the Switch are bound to come out regardless.
