First, this is not “my” keyboard; I own one, but have nothing to do with the design or the production or anything.
Second, I guess you could reach 200wpm on an Ergodox, macros and the ability to remap the layout to something like BÉPO or DVORAK could be useful.
But, frankly, I never tried reaching insane speeds like 200wpm so I’m no authority on the subject.
What do you currently type on?
