>the screen has the same absurdly-wide aspect ratio common to so many PC laptops

I don't think that's right - pretty sure that the X1 Carbon has a 16:10 screen rather than the typical 16:9 one.

There are multiple X1 Carbon models. I Googled this and it looks like starting with the 9th-generation model, Lenovo finally got wise and switched from a 16:9 to 16:10. This is an improvement and I'm glad to see it, but I prefer the 14:9 aspect that's common on current Macs.
