What do you think about Linux systems?

That's true. Even if you don't have some drivers, it's easier to install them than in Windows. First of all, it's definitely easier to find them.

Typing something in the console is more difficult for many than performing a few manipulations with the mouse. It's not that easy to type a file name.
Easier to find? Drivers for Windows will definitely be on the official website of the program/software, but for Linux, they will be in a separate place, and it's not even a guarantee that they will be there.

There are also graphical utilities for such things, if that's more to your liking. I don't even know where you had to search and download drivers manually when Ubuntu connects to the nearest official repository and downloads drivers from there.
By the way, what hardware are you having trouble installing drivers for?

I'll look for utilities; I don't want to mess with the console right now.
The problem is that my network card is also Nvidia.
Actually, all the problems are with Nvidia.

Please provide an example.

Photoshop. Will that do?
Miranda. And even Linux users admit that there's nothing better. "Kopita" is not quite the same, and it's an order of magnitude, or even several times worse. I'm too lazy to look for links.

You can run any Windows program fully, if someone really, really needs to. The question is, why?

Not all programs work as they should under Wine, according to Linux users. Digging into the source code?
Why? If there's no alternative that I like better.

I'm just saying that Linux also has its drawbacks; it's not perfect either. And it's definitely not for the average user, but rather for the more experienced. But that's just my opinion.
