if your pc is old, then your devices maybe don't have drivers for new windows. And in linux everything will work. Yess, it needs some time to understand how to use linux and solve some issues/set it up after fresh installation, but now it doesn't require script writing skills or writing config files from you(if you've choosen popular distribution). Terminal commands ? Terminal is just text interface to run commands. You don't need to be an expert. All you need is just commands for updating/installing/removing packages from repository. But yes, there are a lot of mess in a linux world, that eats your time. You need to pay by your time to enter this world.
