It's good to see that the physical escape key is back!
The keyboard vim was designed for had ESC where tab is on modern keyboards.
The biggest problem with a number pad on a laptop, is it puts the rest of the keyboard off-center from the screen. No way around that I can think of.
Because I (and other professionals) use them. What kind of question is that?
I'd much rather use a generic $10 USB number pad if I really had to do a bunch of data entry. Or sit down at a desk and use a full size monitor and keyboard for that task.
