The very noticeable latency that can be observed between the moment when you press a key and the moment when, far too many milliseconds later, the letter appears on the screen. I suppose it's subjective/a matter of habit. I have a colleague who uses Atom and I tried it on his workstation, because I desperately wanted to like Atom so that I can finally put Emacs away and leave the 1980s behind. He swears it's fine, but the lag is driving me mad. I'm not a super fast typist (110-120 wpm on a good keyboard, and I certainly don't type that fast when I'm coding because I don't think that fast). But I don't look at the keyboard when I'm typing and the lag is very triggering.
