He's right about the new keyboards on ThinkPads - fortunately I use mine with dock and external keyboard most of the time, but every time I am forced to use it without dock it's infuriating how much worse the keyboard is compared to older models.
Sadly yes, I'm still using my x220 rather than move to a x260 because of the keyboard.
I'm on a x200s. Except for a brighter screen, I'm not missing anything though.
Some of us like the new Thinkpad keyboards.
Yup, I love my keyboard on my Thinkpad Yoga 15. Though since it's a 15 inch laptop, my fn keys are grouped by 4, I have a full num pad, and the key spacing feels correct. I went through four laptops before this one and kept returning them because either their keyboard was literally poop and didn't pick up the spacebar all the time, or the screen was so flimsy I didn't trust it in a backpack. The HP Spectra was really nice, but it was too small and the keyboard was the worst. They've improved the keyboard a tiny bit since then, but it's still mediocre, especially for a premium model.
The point is not that it's not better compared to other brands (it mostly is). The point is that it used to be better.
Personally I prefer the new Lenovo keyboards better than their old ones. But it's a close call imo
