Amigasociety, I think the big difference between Apple circa-1997 and the Commodore/Amiga brands today, is that Apple didn't have enough to time to be seen as retro or fall out of vogue.
Commodore/Amiga have been out of the public consciousness now for 16 years! A 20-25 year old today has probably never heard of them. Too much time has passed for these brands to be seen as anything more than a "retro" product, I mention Amiga to any of my friends or on forums and the usual response is laughter, "lol I remember those machines! Lemmings, sensible soccer etc", but they're not taken seriously.
It's a product from an era-gone by, but relaunching Commodore/Amiga is akin to a boy band from the 80s getting back together and trying to be current, it's seen as a bit of a sad joke to most people, they flop and they're back to doing 80s revival gigs in their 40s/50s in nightclubs again within a few months.
Simple fact is, Commodore/Amiga are not cool marketable brands in 2011.
