I'm getting ready to sell my 16:9 thinkpad carbon x1 for the 16:10 nano or x1 2021. I'm OK with my 16:9 43" monitor because it's so big I get the vertical real-estate but my thinkpad feels as though it's really only useful for watching 16:9 videos which I don't do.
If 2021 is the year of 16:10 for Thinkpad, then I'm hoping 2025 is the year of 3:2 and maybe hopefully sometime in 2030 we'll be full circle back to 4:3!
