Mathematica enables me to do things expeditiously that would take a tremendous amount of effort to do otherwise.  So I love Mathematica. I wish I'd had it when I was in college.

The fonts and text color used in the new default style are ugly.  Moreover, opening an old Mathematica 8 default notebook in Mathematica 9 changed all the fonts and colors to the new undesirable ones.  I complained to Wolfram (apparently I was not alone) and a workaround was found
 by including the Mathematica 8 version notebook as a style that one has to select (as opposed to the default style). So Wolfram was responsive, but the lack of foresight remains: Why not reverse roles and include the new default notebook style as an option and keep the old one as default?  This would address one aspect of stability that David eloquently describes.

I would agree about the instability of Mathematica 9. I have posted
previously about the program freezing sporadically with subsequent loss
of unsaved work. I was not the only one to have a similar problem and
post it on the discussion group. However there was no response to my
questions. I am currently working on a note book that I have to restart
several times per hour as a result of crashes/freezing. It seems to be
related somewhat to dynamic content, but as I am unable to reliably
reproduce the behaviour I can't post the problem or contact technical

I for one would welcome an update that fixed any instabilities.

On the other hand I am already using functions new to Mathematica 9,
such as ContinuousMarkovProcess, so the addition of new functionality is
also welcome. I have little interest in Mathematica for an I-pad or
telephone, which I regard as largely a gimmick.
