No, the Switch is not such a device.
The article is very obviously about PCs. The Switch is not a PC.
Just because the switch runs a proprietary OS does not mean it isn’t a personal computing device. It can run Linux, it has a CPU and memory, it runs software, its a personal computer for sure.
Yes, it does. It cannot possibly be described as a PC if the end user can’t install arbitrary software without restriction.
Calling a Switch a PC isn’t slightly incorrect. It’s complete and utter horseshit.
If you jailbreak the Switch, you can do all of those things. But by your definition, because I can’t arbitrarily install Windows software on an Apple computer, it is not a PC.
Just because it’s not easy doesn’t mean the Switch isn’t a personal computer. It is a device you can personally own that takes bits and bytes and performs computations with them that results in things like saving a game (data storage), internet communication (network computing), and video rendering (video stream computation).
The ability install “arbitrary software without restriction” is what defines a PC? Now that is complete and utter horseshit. A Chromebook isn’t a PC? A laptop with account restrictions to prevent the end user from installing software isn’t a PC? A desktop running an immutable linux distro isn’t a PC? Quit your bullshit. A PC is a computing device with a CPU and Memory, meant to be used by several people or less at a time, everything else is superfluous.
