Not so. (Score 3)

X is easy to use, if someone sets it up so that it is easy to use. Which means that there are as many different "easy-to-use" setups as there are hackers. To the experienced user, a bad thing about the Windows GUI is that you can't do very much about it. To the inexperienced user, a good thing about the Windows GUI is that it is pretty much the same no matter what box you use. Furthermore, Windows comes ready to use out of the box. X doesn't. And X is not X if you change machines. FVWM, GNOME and KDE look and feel very different, and adding new apps and changing the sysadmin's stupid default setup to one you like is not entirely painless for the inexperienced. Bottom line, X is still a hacker's GUI.
