I grew up using windows and was a fan of it, but now I am a contrarian because of how shitty it has become. The fact that it is widely used is not an argument that it is good. It is widely used because of existing market share and reluctance of change by people.

Even tobacco, the second most widely used drug, has a group of contrarians still today. Amazing.

Being widely used means almost nothing. There's a lot of reasons things can be widely used. Inertia, history, coercion, cheating, lying, addiction.

Windows is the most widely used because of history and inertia. It is not the best option in just about any metric, and a lot of this is objective. It's slow, the software is poorly designed and obtuse to use, and it lacks functionality. However, people already kind of know it, so it remains.

If Microsoft didn't get the IBM gig early on, we would not be using Windows.
