No, it doesn't. I had gen 1, gen 2, gen 3 X1 carbons. Each was flimsy crap. Each was unrepairable. The gen3 literally fell apart when the screen needed to be replaced due to a manufacturing defect. This flimsy build is not a problem with my Apple laptops.
They have become flimsier, but also lighter. I have tried several, and have stuck with my first gen x1. But the newer thinkpads are so light now you can get a like-for-like with an original X1 by replacing it with a T-series.
