The first time it happens, you grit your teeth in frustration, and the only thing stopping you from throwing your constantly miscalibrating joystick / controlpad / puck / trackball / whatever out the window at high velocity is that you might forget to disconnect it from your gaming rig first. I remember playing with lots of cheapo joysticks in the “early” days, mostly flight sims like Falcon by Spectrum-Holobyte , and thought that analog controllers with the little calibration sliders on them were a necessary evil. The early sticks luckily had two buttons(usually), a thumb button on the top, and one on the base. This was fine, back in the day, when there MAY have been up to 15 other commands for the keyboard, when changing radar modes, or going from a Air-To-Air to a Air-To-Ground hug/weapons configuration, but in todays sophisticated sims and flight-oriented games, two buttons, while tap-dancing on the keyboard, is NOT an option.
