You cannot go back after trying it
I did! Used to have a Samsung 49" ultrawide. After using it for a couple of years, I sold it and got a 16:10 32" QHD, which I found worked better for me (+ one or two laptop screens for chat / random stuff when I’m doing serious work).
The biggest issue I had with the ultrawide is that most of the games that I played weren’t optimised for it, especially in some games where things like the mini-map might be at the far end of the screen, or worse, if it was an older game then you’d have to put up with black bars, or play the game in windowed mode.
Serenity for sure. I love the 90s aesthetic and would like to see it make a comeback. At the very least I’d like to see their Ladybird browser become mainstream - we really need more alternatives to the Chromium family.
