it may not be as simple as windows
You would be surprised to see how easy it is to use it. Setting it up can sometimes be a pain, but hey did you ever try to set up a Windows box? You had to learn to install the OS, the drivers, setup the regedit, ...
But I can assure you that once your box is up and running, Ubuntu is a lot easier and more intuitive to use than Windows.
Halla2 rolf is most probably talking about Mac, and yeah, no matter how good Ubuntu got, it's still the ugly-unfreidly-geeky-software-for-computer-freaks when compared to a Mac.
