Are you making this point from the context where you’ve never tried a touch screen computer?
This isn’t an unimplemented theory. You can head over to Best Buy right now and see what it’s like to use a touch screen laptop.
I feel like all this debate is taking place in an odd vacuum where a lot of us are talking about a bunch of potential problems with having a touch screen on a computer and all these problems are already resolved.
Maybe it’s similar to the whole iPhone duo thing where Apple users are just discovering all the caveats of a foldable phone, but we’ve already gone over all of it with competitors.
