Joe,

That might not be true going forward.  What does it cost to run an
hp3000 application nowadays?   IBM has moved on to Linux/AIX/Java.  
How certain are we that IBM will continue to market the os400 version
of the iSeries 2 years from now?   IBM management has demonstrated a
number of times recently its thinking is to not stay in sectors where
it does not make a profit.
