See below for more information about input/display latency.

It's interesting to see that the recorded reaction times have actually gotten slightly slower over the years, which is almost certainly due to changes in input / display technology.

Newer operating systems tend to do more expensive visual effects, which means a longer lag time from the test to the screen.

Also, mobile device 'taps' tend to be a bit slower than clicks. The increase in use of mobile phones likely has an effect as well.

30ms is currently a typical lag for a desktop/laptop.
