How much faster? And how less flexible?
That time is regained zillionfold in development time.
Now compare perl to java, or 4GL. I once rewrote a 4GL project to perl.
Troughput of a typical run dropped from 48 hours to 24 minutes.

I somehow get the feeling that you do not want to learn any scripting
language beyond you favourite shell. Then again, I'm still biased.

I believe the 'used to be'. Get in touch with reality: it's not the case
anymore.

I survey I read today said the less than half of the installed PC's is
capable of running Vista, and less than 6 percent of those would be powerful
enough to run Vista's premium functions. It would not surprise me id the Unix
functionality would fall in that category (from M$' point of view).
If that is the only good thing about Vista, I'll stick to Win2k for the only
Windoze box I have to work with.
