The travel on my Macbook's Butterfly keyboard was like typing on concrete. Even with a light keystroke, it became a source of physical discomfort for day-to-day work. Add in the Touch Bar, and it was quite literally impossible to touch type on that machine.

The modern Lenovo keyboards aren't perfect, but they're comfortable for desktop-esque use. Plus, I prefer the arrow cluster with pgup/pgdn nearby so I don't have to reach for the function key every time. It's also nice to be able to buy a replacement on Ebay for $20, too.
