I disagree. I don't think the X1000 was aimed at revolutionizing the Amiga platform i think it is aimed at a select few people who want one to support their favorite hobby.
You're actually not disagreeing with tmhgm, you're just wording it differently.
As you say, the X1000 is aimed at a "select few people" (that are willing to pay 2000 bucks for an outdated desktop computer as long as it runs AmigaOS). How many of those people are out there? 100? 200? 300? That's not a future, that's a dead end. Not to mention that even if there would be more customers, there are no more CPUs...
As for it being a 'failure' that is a matter of opinion. With a guaranteed sales of 100% for all boards being made i would definitely call that a success.
For the manufacturer, yes. But what about OS4? How long have we been waiting for USB2 support? A decent 2D/3D graphics system? A filemanager that is not a joke? Some sort of concept for the whole desktop environment that goes beyond "let's try another icon set"? A web browser that doesn't suck?
There are lots of things in OS4 that urgently need improvements. Instead, the dev team is working on a port to some very expensive niche hardware.
