The big problem is the clamshell in that design bites into the top screen. Anyone who had certain clamshell phones (mostly the wide screen horizontal ones) or an early model 3DS might be aware of issues that can occur with that. If that could be resolved, then a smaller Switch would be a really good idea. Although I would hope for an improved chipset on all new iterations of the Switch, especially if they are over a year apart. I think Switch as a platform should evolve toward greater power and capability.

Removing capability, IMO, is an unnecessary step backward and should never be done. New iterations should always either retain or expand all of the software that can be played.

The 2DS came out 2 1/2 years after the 3DS released.

The Gameboy SP came out 2 years after the Gameboy Advance released and only 1 year before the GBA was replaced by the Nintendo DS anyway.

The Nintendo Switch hasn't even been on the market for a full year (until tomorrow).  It has already sold about 15 million units already.  Yet, for some reason people insist that it needs a TV only or handheld only revision that 100% breaks it's primary selling feature.  There is no urgent need to meddle with the device form function to spark demand, because the Switch already sparks more demand than Nintendo can handle it its current form.    

Yes, people have different needs and wants, but you can't please everybody.  Consumer A doesn't buy the Switch because it's not handheld only.  Say Nintendo makes a handheld only Switch.  Consumer A still doesn't buy it because now he wishes it makes phone calls.  Consumer B doesn't buy the Switch because it's not home console only.  Say Nintendo releases a home console only Switch.  Consumer B still doesn't buy it, because it "costs too much".  Nintendo drops the price, and Consumer B still doesn't buy it because "it's not powerful enough".  Nintendo knows that the mass market wants the Switch in its current form, as evidenced by first year sales that surpassed the Wii U's entire lifetime.  They don't need to chase after the people who wish the Switch was this, or wish the Switch was that.  You want a Switch that only plays on your TV, buy one and leave it in the dock, because it already can do that.  You want a Switch that is portable only, buy one and only play it out of the house, because it can already do that.  Otherwise, you're not in a market that Nintendo needs to worry about until sales plateau or stagnate.

It isn't just the dock that is the issue. As others have mentioned if the controllers are not detachable then to play them system on the TV you need to purchase or include a separate controller.

It goes against the supposed all in the box nature Nintendo is trying push.

No, if Nintendo markets the "Switch Lite" as a handheld (which is 100% compatible to games of the hybrid version) and 3DS successor, they don't have to include a dock or an additional controller!

Switch Pro Controller, Joy-Cons + Controller grip and Switch lite dock/cradle would all be optional accessories to add the TV mode later.

The entry price of the base Switch lite could be kept low without selling the hardware below production costs and they could advertise the low entry price. Households with several players/children would be tempted to buy more than one system that is compatible to Switch games.

One Switch "device family" with different form factors, all can play the same games. Just like iPhones and iPads which both have their advantages and disadvantages, but can play the same games.

Oh.

Your username is misleading then :P

Upscaling. I do not expect the games to actually operate at said resolution, nor would they need to either.

The point is, I don't want the portable crap.

Don't assume the consoles I play.

It was a special case? Yet Nintendo did a similar thing with the DSi... But okay then.

And you are under the false illusion that I care what you think.

Not sure how much simpler it can be broken down.
The current Switch doesn't exit the market.

Thus nothing changes for the Switch, just more options are available for more consumers. That. Is. It.

The goal is to please as many people as you can.

But why should I? Why should I pay for features that I would never use like the Screen, Dock, Battery, Joycons and so on?

I never said I wanted a portable-only switch, but thinking on it... Sure. Why not.
Essentially I wanted a Switch XL because the 6.2" 720P screen is shit.

Is this desire for a redesign coming primarily from handheld owners who are upset that they're not getting a 4DS? Serious question and not meant to be an attack.

It seems to be coming mostly from people who care only about the portable aspect, or only about the console aspect, but not both.

Given that the OP's pic only cares about the console in 2d why not redesign systems like the X1 or PS4 where you simply cut the entire system up into 1" square box's and stack them on top of each other, would be completely possible to redesign the ps4pro to be 1"x1" in size! Very convenient for users.
