The thing is you have to type differently on it -- no more banging down your fingers as you might be used to, just a very light touch that, once you get the hang of it, feels so much more graceful and civilized -- and no longer any strain in my wrists.
But I think a lot of people either don't realize they need to change the way they type physically, or are resistant to it. It takes a couple days to change your habits like that.
Tip: if you're one of the people complaining about the butterfly keyboards being loud... they aren't if you use less force.
