I don’t know what you mean by “market realities”. If the market wanted convertible laptops it would be willing to pay more for them.

For me it’s because my workflow is keyboard driven and I fined touchscreens annoying.

On the laptops I’ve had I generally disable touchscreen because I have no use for it and it gets in the way.

I want a good screen, a decent keyboard and a good trackpad. That’s it.

The reality that a certain crowd, I count myself among them, has to/or might have to choose laptops because machines in their preferred form factor either a) implement too many inacceptable but technically entirely avoidable compromises, or b) don't exist at all. That market reality. Like, when you have to settle for a laptop.
