  Maybe you should learn about programming first. I happen to know the A500
very well. What has it got to do with the fact that the Amiga handles
multitasking better than the mac? Outline font technology has little to do
with it unless Apple's implementation is brain damage. You only have to
compute an outline font when a program needs a new metric, and even 
then a caching mechanism would help out nicely. For outline fonts to
_continually_ bring down system performance, the implementation
would have to do something stupid like waste lots of CPU cycles between
each CHARACTER printed (e.g. calculate the character each time it is
printed rather than calculate a large area of the font and cache it)

  I know several people who are no longer running system 7 and have
switched back to 6.0.x because it was incredibly slow on their machine, sucked
up huge amounts of memory, and didn't work with several popular programs.
