The Ergo 4000 is the keyboard that made me rage quit Microsoft keyboards. As far as I&#x27;m concerned it&#x27;s the inflection point of the race to the bottom in the MS keyboard group. Bad key travel, bad decisions about keyboard layout, generally crappy build quality.<p>MS keyboards are frustrating. Their latest attempt at an ergo had a lot of promise, but they nerfed the function and escape keys to the point of unusabiity. (I know that F-keys are awful, but all of the software I use is addicted to them, so...)<p>I would pay quite a bit of money for a keyboard that didn&#x27;t suck.<p>I just want a vanilla split keyboard with decent key travel. And it looks like I&#x27;m going to have to start building keyboards myself to get one.
