As long as folks don't stop me from running whatever I want, I don't 
care if you use bash, but it really irks me, that most Linux systems are 
broken in that respect: Most of them break badly in random ways, if you 
don't run bash as your shell.  That's poor programming practice, but the 
Linux programmers, since they all run bash themselves, they don't see 
the results of their errors, and they all claim its not a problem.  Try 
running tcsh there, you'll see what I mean reasonably soon, when you 
begin to get random weirdnesses...
