I think it might be that you grow up with this computer and fond childhood memories just won't go away ;-)
It's was also an technology enabler.. ie "From using a Schneider 286 PC with monochrome monitor to an Amiga". With multitasking stereo sound and colour video.
BUT I strongly believe it's about that the modern computers has alienated the users. People don't know how they work, software is huge blob of cpu waste.
* Tinkering friendly, ports and I/O which are easy to use.
* Open documentation.
* Communication that is meaningful. (ie not 1st line "support"

* Software/Hardware that does something truly unique and don't backoff from doing something really new/cool/smart.
* Feeling of PC communities being more Bread & butter than Amiga.. "Let's go to the moon".
Let's keep in mind that the days of unsmooth VGA with EISA bus, Resistor A/D sound, arcane system organisation etc.. isn't that far away!
