This irks me as well. Even if it has a numpad, I’d still prefer the trackpad be in the middle.

It has anumeric keypad so the touchpad is in the correct place.

It's the number pad that's in the wrong place. It should not be on the laptop.

I've got a HP with a number pad because no 15" model doesn't have one. I never use it (the number pad) but I have to shift the whole machine to the right to have the touchpad and the "real" keyboard in front of me. So most of the vern is on the right of my eyes. Great design!

Different users different requirements.

I bought Lenovo Thinkpad P50 instead of Dell XPS because the Thinkpad has a full keyboard.

Agreed about the requirements, but do you also shift the laptop right or bend your arms and shoulders?

I'd sell the numberpad as an external device. People that need it will buy it and place it to the right of the laptop (or maybe to the left for left handers, who knows?)

There is another design problem: it could shield the ports on the side where it is placed.

Another solution: engineer the screen so that it can be shifted 1/3 to the left when the laptop is open. That will align it with the spacebar and the touchpad.

About the XPS, I didn't buy it back in 2014 because the then current model had some thermal problem and because I like 3 physical buttons on the touchpad. HP ZBooks do have them.
