These are business class laptops, there's no dedicated GPU. Where are you're going to utilize this high refresh rate? I'm pretty sure 99% of the time the integrated graphics would be working hard to churn out 120 frames of static views.

I bet the vast majority of people would be perfectly happy to have 60hz display, longer battery life, and save a few bucks at the same time.

Funny bonus anecdote: I reinstall my OS in december, only a few weeks ago did I realize it wasn't set to 144hz but 60hz, since I was busy with work since and didn't play any games I did not even realize.
