I think a switch TV is the better choice market wise. A much cheaper and smaller unit.
But the only new switch model I would buy at this moment would be the one described in the op. A handheld unit small enough to fit in a pocket. i do not know if this is viable though, mostly because it would need a smaller battery and the playtime for switch in handheld is already on the shorter end. I still prefer bringing my DS lite when travelling since I can play that thing for 15 hours+ on one charge.
