Why is it that everyone thinks things aren't necessarily done anymore?
This is the reason why we end up with *bloat* these days - people keep
on thinking it is the norm for everyone to have a computer that is
less than 3 years old.

For those of us who like not to waste, or those unfortunate not to
have a few hundred dollars spare, the statement that "disk is cheap"
(or CPU, or RAM) is a bit of an insult.

Hell, my 486 router can't even have more than the 8Megs of RAM it
already has added, due to bios/MB limitations.


Similarly, those of us with 17TB of RAID, but wanting to create 30TB
of data (on a university budget), also find compression fairly useful.
As it is, I have to write ugly hacks to get my fortran programs to be
able to make use of a pipe to gzip - my data is sufficiently redundant
that I get a good factor of 10 saving.
