And don't forget the memory management issues we had to deal with on the PC versus the Amiga. I'm sure we all look back fondly on expanded/extended memory.
While the PC was 'worse' in having two types of memory to pick from above the 640KB barrier, the amiga also had to deal with Chip RAM vs. Fast RAM... the custom chips could only interface with the chip RAM IIRC.
Workbench wasn't bad, preemptive multitasking was nice too, but there was pretty much no memory protection -- a single bad app could hose everything.
Anyway: being a major Amiga fan back in the day, my thoughts on this latest revival attempt: *yawn*
Just let it die alright.
