This argument is so silly. If you believe hybrid Video game system can exist Switch is one. If you believe it can not exist Switch is just a portable. Pick one and stop arguing. 

Whatever you want to call the Switch. I like to call it...The Switch. It's in the name of what it does. It has sold 80 million units and still strong as ever. So you can debate semantics till the cows come home.

By this definition, no PlayStation home console or handheld console, no Xbox and only a few Nintendo consoles are dedicated devices.

Most of them could play music, play movies, show photos and/or had an internet browser.

PS1 f.e. was a nice CD-Player.

Well. Hybrids can exist.
You have Hybrid laptops for example that transform into a laptop or a tablet...

In the Switch's case the Dock is just a "dumb" device that parses Video/Audio to the display from the handheld, all the magic happens inside the mobile handheld device. - If Nintendo weren't locking down the security there would have been absolutely *zero* technical reason why we couldn't use a USB-C to HDMI adapter to do the same job... But you know, propriety peripheral bullshit is the norm in this industry.

Plus we can unlock the Switch's clockspeeds and run Docked performance in handheld.

The dock is literally a convenience device, nothing more.

But you are correct that the back and forth is essentially redundant at this point, clearly minds cannot be changed. (Although I am open to it if the logic presented itself.)

Can that be done without the purchase of any accessories like the Switch?

Can that be done with the Switch without any accessories?

The Switch dock and the Joy-Cons and the cables are also accessories you purchase:

It doesn't matter if you buy them in a bundle or separately from the main device.

Yes.  The Switch comes out of the box with a dock and the controllers are removable.  

I bought a Switch at launch, hooked it up to my home theater in the same fashion I did my ps4.  I played Zelda on my TV just like I would with any other home console, without purchasing anything extra.  

The system is designed to function (out of the box) as a home console or portable console....  almost like it is a hybrid console 

*jazzhands*

No, you didn't hook the Switch up to your home theater without any accessories.

The dock and the the controllers and the HDMI-cable and the USB-cable are by definition accessories.

Ok, and the ps4/ps5 require accessories as well via HDMI + USB cable + controller.  So your point would be???  The ps5 isn't a home console?

You are beginning to get it.

• a PS4 requires accessories to hook it up to your home theater and play it with controllers
• a PS5 requires accessories to hook it up to your home theater and play it with controllers
• a Switch requires accessories to hook it up to your home theater and play it with controllers
• a PSP Go requires accessories to hook it up to your home theater and play it with controllers
• a tablet requires accessories to hook it up to your home theater and play it with controllers
• a smartphone requires accessories to hook it up to your home theater and play it with controllers

So the requirement of accessories is NO DECIDING FACTOR if a device is a hybrid or not!

They all need accessories to get that job done.

YOUR point was that the Switch is a hybrid since it doesn't require accessories to hook it up to your home theater and play it with controllers.

My point is, that your reasoning is deeply flawed.

If the Switch dock would include an external GPU for more differences than overclocking the SoC, THEN I'd consider the Switch as a hybrid between home console and handheld console.

Laptops with an external GPU-box I also consider as a hybrid between a laptop PC and a desktop PC:

We can already unlock the Switch's clockspeeds and run docked performance in handheld mode... without the docking station.

The dock is literally a convenience device, nothing more. Similar to a PSP Go docking station.
