I don’t think I could use another OS that can’t look like the Windows UI. I’ve been using Windows since Win 95; it’s all I’m used to.
As far as PCs, I built my own gaming-capable PC for around $550 - AMD is the way to go for budget builds.
My friend has told me about multi-OS systems. Far too complicated for me. I’m talking about Linux, Windows and iOS.
The Mint Linux UI is very comfortable for me as a long time Windows user.
