Yup, I'm actually a pretty heavy Vim user. I did the whole "remap caps to escape" thing long ago, so not having a physical escape button wasn't an issue for me.
Function keys have been replaced by touchscreen equivalents, but that's not all they are. Some of the buttons act like sliders, so you can actually press-and-slide them (like volume), which is faster than repeatedly tapping physical buttons to do the same thing.
Being able to customize what buttons appear is also great because I can now have a lock screen button that I tap to lock my laptop.
