they do, but experience has shown it is prudent to be able to
administrate the hardware directly from the box. I expect trend of
desktop style management to continue (for the record, I would really
prefer these devices to present html interfaces vs. java).
Also, I just checked cpu usage of X on my desktop and it was using
0.03 seconds of cpu time every 20 seconds or so, or about 0.18%, some
of which was used to update top on screen (i was running a failsafe
terminal)...gdm, etc are completely idle. ubuntu, at least, gives you
nothing you have to turn off.
I'm actually recently converted from the 'anti-x' camp. This is
because I'm now using linux on a desktop and found it to be remarkably
efficient but also was recently in a situation where I regretted not
having it installed. I completely understand and sympathize with the
other side of the argument however. I just don't care anymore, maybe
I'm getting old :-).
