Could be, looking back the ones I have are X220, not X240.
Saying that, modern touchpads are better than old ones generally I find. I've not used any laptop with a keyboard as good as the X220 though so swings and roundabouts.
X230 (and I think t430 etc) are the last classic touchpad and keyboard, still very popular for that reason. I think touchpads improved again with X250 or X260.
I only have X41, X61s, X240, X260 at the moment though.
