I disagree mightily with that, but anyway....

Hasn't matlab been object based from the get go? For example, the standard out-of-the-box
"plot" in matlab (or , at least, the window that the plot is displayed in) has the
functionality that I lay awake at night dreaming about for IDL plots. You can zoom, change
the line properties, print, etc. You can probably create legends too (but I'm not sure).
This is how a regular old "plot" should work in IDL. I guess iTools are the attempt to do
this in IDL.

As to the OP question of "why do non-envi users use IDL" ? Well, in my case, it's because
the matlab licensing procedure appears (horror of horrors) to be even more labyrinthine
than that for IDL (how can that be!?!). Oh, and:
- I have a crapload of IDL code
- Everything in matlab seems to be a string, 4-byte integer, or 8-byte real. What's
the go with that?

It's not intrinsic though - a learned response *can* be unlearned (be it computer
languages or religions). Once the aforementioned inertia is overcome, of course. (For
some reason the the song "We shall not be moved" just popped into my head.... :o)
