Agree with this, it shouldnt be a big deal. Will be interesting to see if Sony and Microsoft go the same route with Pro models this gen aswell.
As far as Nintendo goes, why would they? Their fans are hoovering up antiquated stuff they put out, so they'll probably take Nvidia's old leftover again in a few years. Rinse and repeat

.
You're certainly not wrong. In fact, the market is telling us (you and me) that we're basically wrong. Nintendo is obviously at a good price point. The hardware is basically justified by the cost--you might find this controversial, but they obviously chose to prioritize certain features and novelties while keeping it within the $300 price point. I think there's just over $250 in hardware at the time of the system launch, so it is what it is.
I wish that it was a better package, but there is some assumption that they got a good deal on the Tegra X1's, and we can hope that they'll get a similarly good deal again on a newer SoC. FWIW, I do feel like Nvidia has provided Nintendo with good value (including the engineering support for the hardware drivers) even if the X1 is relatively weak compared to home console SoCs.
You might possibly build a more powerful handheld in the same basic form factor as Switch in that $300 price range, but it wouldn't have the HD rumble. I think they paid a bit of a premium price for that, and maybe I wouldn't have but then we see a successor of that feature now in the PS5 controller, iirc.
Some of that antiquated stuff, btw, kicks the shit out of the new stuff. A little over a year ago, I played through and beat Yoshi's island over Christmas while away from home. I hadn't gotten to do that before, but what a masterpiece that game is
even today. If only it didn't take them just as long with a BotW sequel as it took them to make the first...
