"Amiga never has competition. Amiga is unique".
Except for Atari STs, Macs, PCs... each have their own qualities, and if they offer a choice to the consumer, they are competition.
Personally, I think Amiga could easily make a comeback if they try hard enough.
If you really, honestly, think that AmigaOS will ever be as big or as ubiquitous as Windows is now, you are sadly mistaken my friend. Just to become as popular as Macs would take nothing short of a minor miracle.
Don't get me wrong, I am a big Amiga fan, and I love using and developing for Amigas (and will continue to do so for the foreseeable future), but to be as optimistic as you appear can only be described as hopelessly naive and unrealistic, if you ask me. But, if it makes you so happy to be so sure of the Amigas outright superiority over everything else, inspite of all the evidence to the contrary, then go ahead. ;-)
