In spite of wxGUI, GRASS remains fundamentally a collection of

I make use of this property daily. On MS Windows, GRASS should by
default behave like a stand-alone application. You can make use of the
collection of command-line modules through the msys shell, but that is
really only for power users.

If I'm likely to perform the same operation more than once, I'm *much*
more likely to use the scripted approach than the pointy-clicky GUI.
As an experienced *NIX user, yes. Not so Windows users, many feel
alienated by a command line. On Windows, GRASS should behave like a
self-contained GUI application. There were even suggestions to remove
the command line interface completely from winGRASS because it
confuses users.
So, actually here the debate is about whether GRASS for Windows should
be a different beast than GRASS for *nix/Mac. In my practical teaching
experience I would strongly plead for having them as similar as
possible. Learning on one platform should allow you to use GRASS on any
platform.
And, in my experience, I've never seen users confused by the command
line in Windows. They might ignore it, it might scare them a bit, but
I've never seen it cause any problems. On the contrary, I've always
found that with a little gentle introduction, students very quickly see
the advantage of the command line over the GUI.
IMHO, what you say is that GRASS and MS Windows are incompatible by
principle,
Not at all. Windows does actually have a command-execution mechanism
(even the Mac has one nowadays).
Any installed Python interpreter does not know about any other
packages relying on it. The Python interpreter can change any time
(version, architecture), or disappear, without other packages knowing
about it, then there is a problem. Windows applications are by nature
stand-alone applications, they don't know about each other's
existence.
In what ways is this different from *nix ? GRASS has no knowledge or
control over the Python interpreter. It's up to the user to install the
correct interpreter and make sure that GRASS can find it. Luckily this
is often taken care of by distribution packaging, but it's still
independent of GRASS.
