You are wrong on so many levels, the standardized way to install drivers is through your distro's package manager, I can kill a process very easily- how I do it is open a terminal (super+enter) type "htop", use arrows to find process, press f9 and then enter. Wow that sure was hard, I am literally shaking right now with how hard that was. The UI is much better than Windows, you have things like the qt and kde frameworks that applications are built upon which are way more stable and themeable then windows. Windows is dying and GNU/Linux will take it over. I have been using GNU/Linux as my main OS for a few years now only needing to switch to Windows for things like Premiere Pro as it doesn't work in Wine yet, but once the Adobe Suite is ported to Linux there is no going back to Windows for me, and I'm sure it will make a lot of people switch.
