If you have an iPad, you can use the app Duet. I used it for college back when I only had a laptop and and iPad and it worked surprisingly well.

There’s some lag and you’ll need to install some software on the PC as well, but it’s pretty lightweight if I remember correctly

I think that in an already niche market, it is hard for the average consumer to even further differentiate them into their own niches.

Plus, they’re in the same market. I can’t see someone owning both because they have completely different use cases. If you buy one of them you basically already can do most of what the other one can.

It’s kinda like comparing a Honda Civic to a Ferrari. Yeah they are different, but they are still cars and have a lot in common.
