The T520 mentioned above is the last in the T5x0 line before Lenovo started changing the keyboard layout and action in a way that seemed anti-ThinkPad. Same with the move from T420 to T430, so your T480 was a few generations further along an anti-ThinkPad path.

Personally, I'm currently standardized&stockpiled on two legacy ThinkPad models, and one of the reasons is keyboards. I also transplant keyboard parts manufactured to T60 specs, into later models, because Lenovo started making the keyboard flex-prone, even as the part was otherwise equivalent.
