What's equallt bad these days is the fact that the calibration UI is hidden in the third or fourth level of nested dialog windows recent versions of the Control Panel. Even finding it is a hunting game.

Many, but not all recent game controllers come with accurate and stable enough calibration so that you don't need to do this very often or at all. It's mostly older hardware that needs to go through the process. Most 10 year old controllers (sticks/wheels etc.) can still be perfectly usable today after calibration!
