Linux got pretty stable on desktops, even older people can find their way around it these days. There are some great desktop Linux distros out there, the reason that I say they can be a hassle is hardware detection and support. I have two laptops on my desk right now, and I have at some point tried Linux on both of them, one has a touchscreen and none of the distros I tried would support that, the other had sound issues and the fingerprint sensor was not supported.
