Looks interesting, but I do find that scissor-switch/rubber domes are best suited when there is a very short key travel. I'm curious as to how it feels and sounds.
I have a T450s and the keyboard is quite good, although I wish that the keys weren't glossy but instead textured (like they were in all the photos on their website!). Turns out non-backlit get textured keycaps while backlit gets glossy.
