A good roundup of thin client computing for the uninitiated -
but untrue statments such as

'although the window manager provides the fundamental functionality and the major aspects of the look and feel, that is not enought to consider it a fully usable system. The desktop environment completes the user interface with utilities, such as control panels and toolbars, and basic applications, suchas calculators and text
editors'

are bogus and misleading, and I believe to be rooted in a
misconception that a computer should look like MS windows where
version >= 95. In fact, some might consider that 'a fully usable system' need only provide a single tty login, but since you're
covering graphical interface systems I wont argue -that- particular
point. The main reason I got in to free unices is that I could make them -not- look like windows, so lets not turn off our like-minded audience :)

-Window Manager- based system thank you very much

but again, not to flame, a good review.
