This is a bit unrealistic. Games may work better than they did in the past, but performance isn’t 1:1 yet. More importantly, device drivers can be a lot more dicey.
Personally, the main thing keeping me from actually using my Linux partition most of the time is that my mouse buttons can’t be properly rebound. Yeah, I could find some janky work-around, but that would be eating into my workflow.
I also do, in fact, need Windows for development.
GNU is great, but pretending it’s a viable Windows replacement for every use case is just disingenuous. It doesn’t help anyone and it only makes GNU supporters seem that much more out of touch with the average user’s experience.
There are literally people who will think the internet is broken if they accidentally delete their browser shortcut or just straight up can’t find it in the sea of icons on their desktop. These are the users that Windows is protecting from themselves. The same users probably wouldn’t be able to figure out how to use the command line if their life depended on it.
There’s a place for Windows, and there’s a place for GNU. I’d love to see the place for GNU expand and the place for Windows shrink, but that doesn’t make it so.
