While I am not a scientific user, I occasionally have a need for
something like stats, linear algebra, or other such functions. I'm
happy to install something (I'm using Python on Windows, so when I
say "install", I mean "download and run a binary installer") but I'm
a casual user, so I am not going to go to too much trouble.

First problem - no scipy Windows binaries for Python 2.4. I'm not
going to downgrade my Python installation for the sake of scipy.

Even assuming there were such binaries, I can't tell from the
installer page whether I need to have Numeric, or is it included.
Assuming I need to install it, the binaries say Numeric 23.5, with
23.1 available. But the latest Numeric is 23.8, and only 23.8 and
23.7 have Python 2.4 compatible Windows binaries. Stuck again.

As for the PIII/P4SSE2 binaries, I don't know which of those I'd
need, but that's OK, I'd go for "Generic", on the basis that speed
isn't relevant to me...

There's no way on Windows that I'd even consider building scipy from
source - my need for it simply isn't sufficient to justify the cost.

As I say, this is from someone who is clearly not in the target
audience of scipy, but maybe it is of use...
