Well, long time ago I was hoping that PPC will free us from Intel
misery... Now I am old and not that optimistic.

Well. Configuration I had in mind had 500MHz and 512Meg. It was over $4500.

When did you start? The last time I played around with IDL on Linux
was more then 2 years ago. I manged to crash it more then once not
doing anything radical (in terms of memory allocation etc...).
The graphics problem was extreamly irritating as well. It just did not
feel like a finished product. The Matlab that we used at the same time
looked much more mature. In fact I do not remember Matlab _ever_ crashing
on either me or anyone in our group in the last 4+ years we are using it

I heard that Matrox G450 supports overlays, is it true?
Soon after my last evaluation of IDL I read a news that XiG (or whatever
it was called back then) released AcceleratedX X11 server that
emulated overlays in software.
