One of the few things I'd change about the X220 is the strange 2-piece lid. (What looks like a cosmetic flourish in the lid is actually a seam.)

Two of the four used X220 units I've bought arrived with the lid end piece wiggling, because it was no longer firmly attached to the main piece.

The X200 and almost every other ThinkPad managed just fine with a 1-piece lid, including being rugged against drops, so I don't know why the change.
