The numero uno reason I want shell access is, thanks to Karl Friesen,

I'm a PINE snob, and I like having the majority of my mail in one
place.  I also like the "portability" that server-resident mail offers.

In addition I use my shell account on an almost daily basis for things
like NSLOOKUP, pings, traceroutes, and ftp.  I am aware that
"non-shell" alternatives exist for all of the above.  However, beyond the
fact that I learned to do all these things in a shell environment, I think
using shell for these things simplifies troubleshooting.  If I'm testing
a new FTP account for access rights and functionality, I'm going to test
via shell so I can cut application out of the troubleshooting picture.

I also very frequently use my shell account to test website
availibility.  In many cases, I can't verify website _functionality_
(links and lynx are what they are).  BUT, I can prove that a specific is
or is not public accessable.

Just some quick thoughts...
