...Not to mention AIX and IBMi systems.   I would agree that laptops 
where probably the biggest reason for the swing as they where already 
seriously lagging behind and no suitable replacement in sight on the 
PowerPC side, but there was also little chance of a follow to the G5 
that would be suitable for Apples needs.  The G5 is a stripped down 
POWER 4 processor that IBM also used in some low end systems aimed at 
the technical workstation market, that was already rapidly moving 
towards the lower cost Intel platforms.  When POWER 5 came along there 
where no models aimed at this market anymore.
