Examples of good User Conceptual Models

Or to further the idea. On most 7-1/4 diameter saws.

I wonder if Skill was the first company to have a blade depth adjustment handle (usually near the Grip of the handle) that cammed a nut tight for blade height.

Today I believe 100% of all companies adjust blade height that way. It honestly sucks because the carpenter strips the bolt, yet the desigher must not know that that is a poor method for blade adjustment.

Point is-- today there has not been a DIFFERENT way introduced to adjust blade height in 25 years. I think the conceptual model for blade height adjustment is stagnant for that design.

CG, because you brought up Lotus, I constantly still throw an alt-TAB in another program that does not have that function as I would expect.

I think there are examples of change in the conceptual model as well as stagnancy in the conceptual model.

Is that where you wanted to go with this threaed?
