I mean, we are getting use out of PCMCIA now, but it was a (very expensive) white elephent then. The money should have went on fast ram/processor. And they should have had high density floppies and a slimline CDROM slot.
I disagree. PCMCIA slot was much better idea than any proprietary expansion slot. It is just that A600/A1200 was never big success comparable to Amiga 500.
HD floppies could have been nice bonus but it would have been outdated by CDROM/CDRW.
