	Good.  Never cared for bash completion and the Microsoftesque 
penchant for trying to do everything, when some of us only want them to 
keep the hell out of the way.  Every new idea they add just boggs down 
the overall system, rather than concentrating on writing faster, tighter 
code for the user interface, leaving us stuck with chasing down the next 
full computer upgrade just to keep up.  It's stupid.  I can recall back 
in the 80's, having a spreadsheet and having it take 10 seconds to 
recalculate the thing, and then looking at all the advances in Windows 
and CPU processing power, and the same spreadsheet still takes 10 
seconds to recalculate.  It's stupid.  I needed to buy a whole new 
computer because friggin Orca no longer runs worth a crap on a Celeron 
CPU, and it's only going to get worse as time goes on.
