I can't answer your question , however, would like , for what it's worth, to
tell you my experience....
When I first started Mathematica it was frustrating as hell.....the only
thing that saved me from throwing in the towel was Mathgroup....and their
Expertise is FREE....Amazing!!!
After a while I reached the point where you can't tear me away from
Mathematica....there are too many things of value in it for me....too many
things that I can do with it that, by hand, would be abominable or
impossible.....I think Mathematica has endless applications whether
Education or Professionally and is only hampered by the Imagination of the

Frequently when Mathematica is trying to evaluate an expression the CPU
usage on my machine seems remarkably low; one core will be ~70% with the
others only up to ~20%. I'd expect one core at least to be maxed out. The
hard disk isn't being hammered, RAM usage doesn't increase, so my question
is: where is the bottle neck? I'm new to Mathematica so is this normal
behaviour? I'm using 64 bit Win 7.
On a related note some of my expressions just don't seem to ever return,
particularly those involving Sum - again, is this normal?
My experience with Mathematica so far has mostly been frustrating. I can
get it to do dead simple things, but anything vaguely complex it seems to
choke on. Just getting it to replicate what I can do by hand seems an uphill
struggle. Do many use it professionally or is it mainly used in education?
