A problem in Handbook's Common Tasks part

[Marc Fonvieille]

Hello,

I found something "annoying" in the introduction of the Common Tasks
part, I read:

"Describe the X Window System in more detail, and introduce you to
modern desktop environments such as GNOME and KDE."

The X Window System, GNOME and KDE are described in X11 chapter of
the previous part "Getting Started".  Since this sentence seems refering
to the desktop chapter, I'd see something like:

"Introduce you to popular and usesul desktop applications: browsers,
productivity tools, document viewers, etc."

instead of the current sentence.

Well someone should be able to find a better text than mine :)

Marc
