Well, to be clear, I said primitive comparatively. Yes, it's better than using an on screen keyboard and better than many cheap laptops but vs. comparatively priced laptops, it's a big step down.
I was also speaking only to the keyboard and touchpad, just comparing those specific pieces of hardware from a functional standpoint. I won't begin to judge what's better from a use case because as you said, that's going to vary widely between individuals. I personally cannot stand Windows and also, don't find it convenient to constantly shift from keyboard to touchscreen vs. keeping my hands at a keyboard and mouse/touchpad. I also hate having fingerprints all over my laptop screen, but that's just me.
