lol even in 2005 Linux was excellent for most situations. Problem was in a business environment it was usually harder to find someone who has the expertise in Linux but also gaming - the lowest-common-denominator sector of development - usually just prioritizes Windows. This is NOT because it’s “better,” but because it gives them more freedom and they can get shit “done” faster. On the user-side, meanwhile, Windows wasn’t really doing the user any more favors than just working pretty nicely.
But today? Omfg Linux has come insanely far while Windows is what, pretty much you handing over master control to M$ while borrowing some CPU time on your own computer so gracious of them.
Oh but if it lets you play a game then all is forgiven. Lol. Priorities.
