Whoa! I won't embarass anyone by naming names, but someone in this
newsgroup recently suggested that a Mac takes a long time to
recalculate a spread-sheet because the 8mhz 68000 chip is already busy
with the interface. Wrong.
When a Mac is recalculating a spreadsheet, or doing any other computational
chore, the processor is dedicated only to the programmer's code and
any interrupts (such as mouse movement). It is not worrying about
drawing windows or handling menus until the user calls a system function.
If the spreadsheet is slow, it's bad coding. The interface has little
to do with it.
