Your response accounts only for one piece of the experience, which is the muscle memory. Perhaps you move like a robot, and muscle memory is enough for you to precisely strike the small tap targets of a keyboard, but you are off target to tell someone they are wrong based solely on that.
Tactile feedback is a big advantage to physical typing which allows you to know your fingers are in the right place prior to making a keystroke. Without it, you don't know until after the touch has registered. Ignoring that and saying it amounts to nothing is short sighted at best. Even beyond that, there are plenty of people who aren't that coordinated and/or stable, period, which amplifies this deficiency.
Additionally, this doesn't account for the fact that in most scenarios, the person using a mobile device is, in fact, mobile, and may not have a flat, stable area to place the device, but rather they are balancing it on their lap or holding it with one hand and typing with the other. Nor does it capture the fact that when you have the device in your lap, the screen isn't going to be at an ideal angle to view at the same time.
So sure, the same concept applies, but to pretend that the experience isn't inferior is just turning a blind eye to reality, imho.
