The Best: have to agree- hardware (and OS) years ahead of its time
The Worst: marketing, and trying to do PCs at the same time. (ie: marketing years behind its time !)
the PC thing: CBM tried to get into the PC market as that was what was percieved as what the business community wanted. IIRC the PCs were (to put it succinctly) crap.
They could have pushed their one true gem (Amiga) into that market, and perhaps Commisioned a half-decent office suite to be put in a business orientated package.
at the time, a well kitted A3000/4000 was as good as the concurrent Macs, which were running M$ Orifice.
:-D
IMO an A3000 probably could have done as good a job with well written office products (not necessarily M$) as the Apple's equivalent offering the Mac II (ie: the IIci/vi/fx/etc)
