FWIW, the anniversary t25 has the good keyboard. It was expensive though not outrageous, so after talking it through with my wife, I bought it when it came out. It's still my primary driver, I use it 8++hrs a day for 6 years running(with no sign of stopping), so it mostly worked out. It's essentially a t470 so easy to maintain (external battery, SD card, and one screw for ram or ssd upgrade).
Otherwise, everything after the '30 series had the modern random ridiculous layout. We had a standard for decades, then apple decided each laptop will have unique layout and we all blindly followed - muscle memory is for wussies who don't stare at their keyboard to type! Rant rant grouch grouch :)
