An order of magnitude difference in response time has huge ramifications for all sorts of applications.

It's vastly more disappointing. > The best physical reaction time is about 160ms [1] Yes, but you (probably) have 10 fingers, and you can get the gaps between keypresses down to <100ms. That really helps with typing. Suppose you type 200 wpm, average word length 5 characters, maybe 980-1000 characters/minute or about 15-18 characters/second. When typed at a steady pace, you can reliably do 63ms between keystrokes. This isn't reaction time. With EEG, you get like 1 character every 4,800 milliseconds. (Although I admit I don't know if this is using dasher, or some other typing scheme, or what. Do you get just a binary character, or any UTF-8 character in those thousands of milliseconds?)
