Sure.It's far from useless.
Just because Apple refuses to come out with a 2-in-1 Mac doesn't mean there's no use case for them.
Yes they don't replace a dedicated tablet and yes I would not want to use a pen on a laptop all the time. But they are great for quick on-the-fly markups or notes while working on the laptop. If I ever buy a Windows laptop again it will only be a 2-in-1.
I didn’t say anything about Apple.
You’re also discussing the use case for a foldable tablet, not a laptop with a touchscreen. I’ve deployed thousands at this point, the vast VAST majority of users only remember it’s a touchscreen (not 2 in 1) when they accidentally brush the screen.
