The handheld market, the price sensitive one, won't get it at that price. Nintendo will need a handheld SKU for these, probably next year with Pokemon and/or Animal Crossing. Meanwhile Nintendo is For the Gamers. Sony nailed it with this punchline. It fits Switch just as well. So Nintendo fans and non console warriors, who skipped Wii U and have the money to expand gaming beyond their living room. The own "anytime, anywhere" Switch proposal certainly is enticing.
Except I think you're just describing handheld gamers here, to be honest.
Either that, or you're talking about some previously unknown market or subset of people that's somehow immediately on-board with a hybrid device even though there hasn't been anything like it on the market. I mean, it's possible. I just don't think it's all that likely myself. You are clearly among this crowd, but the question is how many others are.
