|Well John, can you say memory management?  Why is it that a 4 meg Mac
|can't run a real multitasking operating system?

The latest rumors have it that Apple will be annoucing a multiasking Finder
soon (possibly this month).  Since they have had one in beta test for several
months now (fact, not rumor), I'd believe this rumor.  It'll be amusing to see
Apple have a multitasking OS before IBM (ignoreing UNIX for the moment).
BTW, memory managment is NOT necessary to have multitasking.  It just makes
the world a little safer.

|It has the wonderous
|68000 microprocessor.  Awww guess what? it can't manage its own memory.
|Segmentation allows the Intel chips to manage their memory.  I suggest
|you put a MAC with 4 meg next to an AT with 4 meg of memory running
|Microport system V or SCO Xenix and place your bets as to which machine
|can start compiling 4 different programs simultaneously. 

But how fast does it compile?  The whole point of computers is not just
what they can do, but do they help you get your job done faster?  I'd give
up multitasking in an instance for a very fast compiler.  Because I spend
most of my time waiting for the compile to complete so I can test the latest
bugs I put in my program (:-)).  And the compiler on my Mac is far faster then
anything I've seen on an AT class machine (including Turbo C).

|What size segmentation would you like?
I don't like segments at all.  Segments mean segment registers which means
extra code to keep track of the registers and extra bugs caused by  not
setting segment registers correctly.
