Yes, there is much more to a mac than NuBus.  Like Singletasking, slow
video which goes through slow NuBus in most Macs, slow CPUs, slow FPUs,
slow SCSI, wimpy file protection, high prices, and an operating system
that is in vaporware neary as long as NeXT existed.  That is why I KNOW
OF about 20 former Mac and PC student users that are switching to NeXT.

The people that don't switch are the ones who have never TOUCHED a NeXT
or are so rabid with pride in their Mac that they wouldn't switch to a
HAL-9000 costing $600
