So you see, the unique advanced architecture is really what made it possible. Now I totally understand when people say this can't happen again because we are pretty much there these days (Windows crashes less, makes a good attempt to multitask even if it is horribly inefficient and even Ubuntu is media rich out of the box...a FREE OS) and so that only leaves price and games playing ability.
I don't think so. A good design (even if it's a dated good design) is a hell of a lot more interesting of a thing to retain and revive than trying to recapture this or that place in the market. Marketing and its tactics leech the life and the interestingness out of anything as a matter of course, so that
actual unique features and quirks can't get in the way of The Plan. You try and revive the Amiga by recapturing its position in the market, all you're going to do is turn it into definitionless mush.
The CPU is not that important if your machine's performance is derived from custom silicon rich motherboard.
As a programmer, yes it is. I
like having a system on which I can easily do assembler, and I like 68k assembler best. The CPU is the lynchpin of any computer design, even a coprocessor-oriented one like the Amiga; it
definitely matters.
