Although it's the article's fault, not the submitter's, I think it's worth noting that the accurate headline appears to be "$5,900 chair may be the tech world's new key to productivity, says owner of company selling them".
JP had this in Grandma's Boy in his awesome techno cave room[1], which is a somewhat unfortunate movie that pokes fun at the personality side effects of people who immerse themselves in technology. I like the movie's themes but I wish the premise wasn't so much about mocking and taking down the weirdo boy genius. I too want robot legs and there's nothing wrong with that!
I believe he finds it funny that the guy spent over 5k on a chair, but uses an pretty unergonomic keyboard. (I have used the new apple keyboards on the new macbook 12'' and imo, it's not too bad once you get used to it. But I'd totally exchange it for some kind of mechanical keyboard.)
The external Apple keyboard is far from ergonomic, its function has always been primarily aesthetic - like the long line of unergonomic but oh-so-pretty Apple mice.
Apple keyboard are made to look good. Good ergonomic keyboards like Thinkpads have key travel 1.8-2mm. Thinkpads will also have keys with rounded edges and bigger spacing between keys.
