You can check their capacities and speeds with software like cpu-z.

You can use windows freely without activating, or at least you could last time I needed it.

This is the correct way to do it, use it, see if it works for you and try to understand what happened. It’s not that different from using examples or stack overflow. With time you get better, but you need to have that last critical thinking step. Otherwise you will never learn and will just copy paste hoping it works

I’m looking for the same. I’ve used moon reader on android and it can sync progress between devices. Also it supports WebDAV, so calibre may work but I haven’t tried it

Put any person who has zero computer experience in front of a windows computer or Linux computer and I doubt they would say the windows computer just works and the Linux one doesn’t.

In my experience, usually with Linux they have less problems and it’s easier to use. Until they need an application that only works on Windows.

Don’t forget the old stuff folder inside another old stuff.

Seriously tough nowadays it seems harder to organize, everything is in the cloud or in an app.
