The Switch is a portable console first that has the option to output to a display.
For all intents and purposes, it's a handheld with a base-station that converts it to a fixed device.

Other NES to SNES Remakes/Remastered games:
* Dr Mario.
* Dragon Quest.
* Fire Emblem
* Kirby Superstar.
* Super Mario 1, 2, 3.

NES to Genesis.
* Megaman 1,2,3.

Probably a few more I forgot... They weren't the rule back then, but they were definitely still a thing.

Just because the Switch uses mobile hardware does not mean it's a portable console first. Their whole approach was "How can we make something that is not a successor to the Wii U or the 3DS". Their answer was the Switch. The entire concept of it was always about it being both, which was not the concept of any other home console or portable console before it.  

The biggest flaw of the Nomad, Game Gear and pretty much all early handheld consoles besides all the versions of the original Game Boy/Game Boy Color is that they had terrible battery life to the point that they really weren't that portable. The Game Boy/Game Boy Color was also much affordable and durable then all the other handhelds that competed against it.

True, mobile technology and miniaturization wasn't really at the point yet where they could make it work in color and especially with a back-lit screen without taxing the hardware too much and thus draining the batteries in a very short amount of time. Which is also partly due to the batteries themselves, those you can buy today are quite a bit more powerful than the AA's you could get back in the day.

That being said, apart from their power draw, they were already pretty great gaming devices. But the battery is also really what killed them.

It's not both.

The Switch is a mobile device first and foremost with the functionality to output it's display.

It is built 100% around mobile hardware, battery, screen, processor, ram, storage... Everything is mobile.
It just has a dock that can pass video onto a seperate display...

* My tablet has a dock that allows me to output to a TV via HDMI to a display. STILL a mobile device and not a hybrid.
* My phone has a dock that allows me to output to a TV via HDMI to a display. STILL a mobile device and not a hybrid.

I even have an Android powered gaming tablet with built in physical controls that also outputs to a display via HDMI... Still a mobile device 100%.

Just because it has a dock does not mean it's not primarily a mobile device.

The fact there are variants which use the *exact* same hardware, the absolute exact, right down to the CPU and GPU type, that are mobile-only, just further reinforces the fact that the Switch is a mobile device, not a fixed home console.

The Switch is an absolutely fantastic mobile device, it's actually a really really terrible fixed home-console from a hardware point... But being able to dock is a value added incentive that sadly not everyone gets thanks to the Switch Lite... Well. Existing.

Off-topic, but if you look hard enough, you’ll find most ideas already existed on Atari 2600 and contemporaries. Even if primitive compared to later technologies. The 2600 had wireless controllers, online capabilities with GameLine (downloading of games to a cartridge) and even had a motion controller that connects to your brain in the works that never released however.

I would put that under false equivalency.

After all, even though you can connect them to the TV, they don't change their behavior (as in, clocking higher or lower depending on if they are docked or not) and more importantly, you don't change the input device. The Switch changes how you play and use it depending on being docked or not, but that's not true for your Tablet or phone.

Didn't TurboExpress launch before Nomad? Like 5 years earlier? Seems like TurboExpress deserves credit for innovating, not Sega.  Sega Nomad was nothing more than a direct copy of the TurboExpress.  

Regarding how novel the Switch is (or isn't), who cares?  It has great software and is selling lights out.  Nothing is going to change that.

Express did not connect to the TV. It was a separate product. Also did not have 2 player.

TurboLink[edit]

The TurboLink cable.

The TurboLink allows two-player play. Falcon, a flight simulator, includes "head-to-head" dogfight and cooperative modes that can only be accessed via TurboLink.^[11] This technology was also used for Bomberman '93 Com-Link multiplayer. It was released after the TurboExpress launch. However, very few TG-16 games offer co-op play modes especially designed with the TurboExpress in mind.

At best the Nomad was a tweaked version of the TurboExpress.  The Nomad isn't as original as people are making it out to be.
