I wasn't just speaking of X11R2, but obviously "acceptable" means two
different things between us.   Even with more (or less), it can take
more that 3-4 seconds to paint a window of text, and not just in X11R2.  

Come on, you can't tell me this is ok to you?

Why not use an X Terminal then?  Why bother with the headache of Sun's
OS and all the related problems?  My biggest point was the state of
thier source distribution, and it carried over to other things.  The only
security problem is that a user could have direct access to a ethernet line
which is a problem with the Sun workstations too.

Considering Sun's claims about networking and their products, that is 
a pretty big thing to just blow off.

I think I voiced quite a few valid complaints and you mostly avoided them
with work-arounds.  Gee, if you don't use this and if you fixed this 
the system is really nice.  And, oh, don't do anything locally, let another
machine do all your work.

Consider programmer-time when talking about price ranges.  I think that
you will find a Sun network *much* more expensive to purchase, setup 
and maintain than a lot of other systems availble.
