3-key rollover instead of n-key rollover?? Pass…

[gwerbin]

How many 4-function calculators have n-key rollover? What would that even be used for? Are you touch typing on the calculator at 100 digits per minute?

I feel like the parent comment was sarcasm

[stavros]

100 digits per minute is less than two per second, I feel like most people exceed that.

I bet watching people use a calculator by poking at it with one finger drives you absolutely homicidal.
