It's like phones with 120Hz displays.

You don't know you need it but once you have it it's hard to go back.

Similarly with monitors, 60Hz LCD panels are OK, but 120Hz panels are just so much easier on the eyes. At least for me. Try dragging windows around or scrolling quickly, and you'll see the difference between 60 and 120 very fast.

I can spot the difference but the value proposition is zilch to me. I would not pay 1 extra cent for it. If I was a gamer this would of course matter.
