I believe the Mac ROM exists in order to make the Mac legally unclonable,
by copyright.

The original Lisa was more powerful, but the Mac came out with 64K ROM,
128K RAM, and 400K floppies, and ran essentially the same interface 
we are now using.  Obviously a great deal of genius and hard work went
into it.  (X windows is how many megs? How fast is it on 50 Mhz workstations?)

The more compact the code, the faster it is (usually!).  Think of the Mac
ROM as a collection of device drivers--the hardest software to write--
with the GUI as one big device.

Nobody else has done as well, for better or for worse.
