I upgraded from an M1 to an M4 MBP recently and although the performance gains were mostly incremental, the matte screen (fucking finally Apple) is really nice and a good reason to upgrade if you ever plan on using it in a brightly-lit area. It’s a must-have.
I switch to 45" UWQHD myself.. slightly taller with bigger pixels for work and enjoy it immensely. I've had a few issues where my vision got dramatically worse a couple years ago so even my 32" 1440p was a struggle at times.
With this display, it's similar to two 4:3 aspect displays in my typical use... my IDE or Code pinned on one side, my browser or another app on the right.
Hmm... I guess someone thought that I was boasting about my setup.
It's really not a big deal. I know quite a few people that have much nicer rigs; especially gamers.
I was really just saying that the MPB has a processor that still rocks, several years later, but the large screen that I use (which is actually not as impressive as some of the gaming screens), has me spoiled, and using a laptop screen feels cramped.
