Not convinced by that, I was a massive fan of that era's keyboard but having recently come back to the fold with a T470P (having use Dell's for most of a decade) I love it's keyboard as well (even the smaller function keys simply aren't an issue once I adapted to them). I still have an old R series with the old style keyboard kicking around and I tried them side by side, it was (and is) a great keyboard but it's simply not better than the keyboard on the T470P in any way I actually care about.
