> In the end it worked, but I can't understand how people can even work with Windows

It sounds like you are far more familiar with OS X and Linux than Windows.

> Installation of Ubuntu is about as easy as it gets

I still have tearing issues on my screen from the graphics drivers that I'm not sure how to fix. Windows has no such issues for me. I know there are issues with Windows too - they just never seem to occur to me.

While I agree this comparison isn't fair to the hard working developers of Linux, it illustrates the point that both operating systems are complex. The more familiar you are, the less problems it seems to have.
