The second or third gen X1Carbon used a clickpad. And an LCD bar for the F1-F12 keys. The two design decisions were reversed in the next iteration of the laptop.
And the designer was fired and got a new job at Apple.
Alas, the L series thinkpads have the trackpoint but rely on the trackpad for clicking. Nice fast machines that have good battery life (e.g L440) but...
There were a couple of those in my last job. But apparently they reverted to having proper buttons.
The T440? They had to revert it for the next generation (T450).
