The X1s have great build quality compared to other non-Apple laptops, but mine didn't last but about 1.5 years of daily work use before the case itself started failing (case metal chipping and bending + keys failing, battery issues, ports failing, etc etc). On the other hand, my 2014 macbook air still looks almost new even after almost 7 years of daily use.
I think it's as close as it gets, but it's still nowhere near Apple. I'd love to see a premium non-Apple manufacturer.
