Well Smalltalk was made to be *the* operating system of a machine. I
don't mind the whole infrastructure as we still have that with Java, C#,
and if you want to do anything useful with C/C++ you have to learn how
to use many other libraries.
I think the only reason anyone complains about Smalltalk's whole
infrastructure is because it isn't hidden from them where as with the
typical language or IDE, all the other libraries are hidden and only
appear when they are used. So other languages/IDEs only *appear* to be
simple and only *appear* to have less constraints.

I felt like that at first. I found it very quick and easy to use though
and I appreciated it more than any Java or Microsoft IDE.

Yeah, the static content had to be imported into the image. It's a tiny
bit of a pain in the ass but I think Seaside lets you add the static
content from the web browser so it isn't too bad. I'll have to take a
look at the code I wrote up to see how I handled it. The advantage for
me was that I could take the image *anywhere* while I was developing and
I had to demonstrate the web application to a few diff people who were
running 2 different varieties of Windows (XP and Vista) while I was
using GNU/Linux for development. Very nice to just move the image around
and knowing that the whole app is self-contained and that I wouldn't
have to worry about missing directories or missing static content.
I'm curious as to how the "hello world" bit was explained. It shouldn't
take that long :S
