Yes, exactly this. I'm using a 10 year old elitebook folio g1. It's about 2 pounds and does what I need it to do. Available with a 4k screen if that's your thing. Does not feel sluggish. Given that I'm not gaming, video editing, or doing local LLMs (and I think there is a big chunk of the population in that camp), I feel like I am missing out on nearly zero.

(And I'm not trying to say anything is special about the laptop I'm using. I adore using trackpoint (so much that I brought my own trackpoint keyboard in to work to use there) so would gladly trade for an old thinkpad if what I had didn't already do what I need it to do).

In the middle of a gaming session one stops thinking about graphics once it's reached a certain level of fidelity, and that level is far below RTX. Not worth the money, especially today.
