Most of the hate I see on the keyboard is from people who've only spent a few minutes on it. After a few days you get used to it and don't even think twice about it. I've regularly measured my typing speed with my old retina MBP and my new one as well as my DAS keyboard with cherry red switches, and I get about the same speed +/-5 wpm across all of them.

I'm going to rant here for a minute: IMO keyboards are a great example of "bike shedding" and the law of triviality. There are tons of options for layouts, key mechanics/switches, etc and everyone has to use a keyboard, so everyone has their preferences. At the end of the day, the only objective way to compare keyboards is by your max typing speed, but this metric is almost 100% irrelevant. When does anyone ever type at their max speed for any practical purpose? For most people, the worst a keyboard can be is mildly annoying. At best, you'll forget you're even using one. Don't even get me started on people who learn Dvorak for speed or practicality...
