As for the other things, I've been wondering, too!
> Why are they so small?
Probably because they're afraid people accidentally touch them? I think if Apple dares to make them this big, that's probably an irrational fear.
>Why are they not centered?
After a _long_ time thinking of it, I got an idea: Maybe they're centered on the space bar to be between your hands when typing? That, however, would also mean that they acknowledge that you're usually holding your hands off-center to reach around the number pad. Has anyone used a laptop number pad in the past 20 years? I agree that they should go in favor of a more sensible overall layout.
People will be subtley dissatisfied with things without examination of why or attempting to alleviate this dissatisfaction.
It is meaningless to posit people are satisfied with the state of things as if this said anything about the value of the current state of things or how people would react to an improvement.
People could have been said to be as satisfied with pocket pcs back around win ce.
After being exposed to a touch screen interface that wasn't completely garbage they overwhelming preferred them and voted with their wallets.
Same with not being able to rest your fingers on the touch bar.
Dragging requires more effort since you have to both move the finger horizontally while maintaining downward pressure, which increases the friction significantly. If the button was separate, you can hold it with one finger while just touching the touchpad and controlling movement with the other.
I'm not sure why Apple doesn't present this as a main option instead of burying it in the settings.
In my opinion, it's a significant usability & productivity improvement. Three finger drag makes selecting text a breeze, along with quickly moving applications across monitors.
Having to maintain pressure while awkwardly moving your finger across the touchpad, while simultaneously appeasing the force touch gods, seems rather uncivilized.
Accountants use them all the time, along with a lot of other people whose job requires entering a lot of numerical data.
