The "latency caused incorrect handling" is IMO the worst thing in all the "modern desktop is slow" complaints.

I can deal with 9 seconds latency, if I can mentally precompute the expected path taken and the results match it - this happens just by being familiar with what you're doing, and can be compared to using Vi in edit mode with complex commands.

I can't deal with 400ms lag if the result is that a different action than the one I wanted is executed.
