It didn't come with one, no, but plenty are available and I use mine just like a Switch with no problems. From plenty of experience having to fiddle with running laptops on bigger screens, it shows when a device was made with seamless screen switching in mind. I don't have experience with the other popular PC handhelds - are they as easy to swap between big screens and portable as the Switch or Steam Deck? My assumption is that they all have that in mind, but maybe they don't.
I wouldn't consider the GPD Win in the same category because it was not designed to easily switch between being hooked up to a big screen or used portably. It's a palmtop computer with a controller embedded in it, not a hybrid. Being able to hook it up to a screen is an afterthought.
Hard to say for sure without seeing a timeline where Nintendo didn't make a hybrid console and seeing if the Steam Deck and other PC handhelds still happened the same way. I'd be surprised if the success of the Switch had absolutely nothing to do with the Steam Deck's creation, however.
The Corporate Oligarchs are the common denominator between the GOP and Democrats. The Democrats, corporate beholden though they are, are preferable merely by not being fascists.
Much as I hate Nintendo now, their contribution to gaming can't be denied. First they revived it from the crash in 1983, then they showed that there's a market for a hybrid console/handheld device, paving the way for PC handhelds.
Are you talking about the MCU Spider-Man? If you want to go there, then every version of Yahweh that exists has definitely killed more people than every version of Spider-Man that exists.
Not to mention Yahweh genocides on purpose rather than by accident.
