What do you think about Linux systems?

That's not true. After I found them, I learned that they also need to be installed, almost from the console.

That's true. Even if you don't have certain drivers, installing them is easier than in Windows. First, it's definitely easier to find them – you go to the distro's wiki, look at the documentation, and see which driver you need for your hardware. I don't think it's easier to find a driver for Windows, unless you have some exotic hardware. And what scared you so much? Is typing "sudo apt-get install nvidia" in the console and pressing Enter more difficult than doing a hundred things with the mouse? Besides, you don't necessarily have to do it from the console – there are also graphical utilities for these 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 pulls the drivers from there.
By the way, what hardware didn't the driver install on?

And in general... most programs are written for Windows, including the best ones...

Can you objectively judge this if you haven't seen programs for Linux? What is the best program in your opinion for Windows?
Please give an example.

...and they can't work fully under Linux.

That's right, why should Windows programs work under Linux if there are Linux programs? And I assure you, you can run any Windows program fully under Linux if someone really, really needs to. The question is, why? There's no denying that it applies to games, but first, you were talking about programs, and second, I wrote and posted a link – games can be launched.

P.S. However, I don't see the point in arguing about this – there are already a lot of materials written about it.
