The Switch works because it limits the options to just games. But for general purpose computing, even my slightly older Android phone can open dozens of tabs, play games, video, drive a high-res display, and so on.
If it had a dock that immediately connected it to some monitors a mouse and keyboard and the UI changed a hair I'd be a perfectly happy computing user and I get to carry around my primary device with me.
In fact, it has similar specs and a better GPU than many low-end laptops that millions of people are reasonably content to use on a daily basis.
Of course, it doesn't imclude the crucial "dock" part (except in the sense you can plug in a fullsize keyboard and monitor as you can for a laptop).
Not sure of the situation recently, but at one time they were topping amazon lists.
