At work, I have a L540. I don't like the look of the new-ish ThinkPad keyboards, but otherwise, the only complaint I have is that a few keys will sometimes (rarely) fire twice when I push them.
Otherwise it is a nice keyboard. Tactile feedback is not comparable to a Model M, of course, but it is okay. Acoustically it works nicely.
I am not sure how much of a difference it makes, but I was surprised when I got my machine to find out it is a 17" model, so the keyboard is rather close in size to an external keyboard, which is very nice. (I don't usually carry this beast with me, so I don't mind the size. YMMV!)
