These "Amiga is Dead" threads show up every few months here and on other Amiga sites. They are a complete waste of time, unless you want to use one of them to motivate people to change their behavior toward participating in some kind of Amiga development, or project (which is not the case in this thread).
I think that the Amiga community is more alive today than it has been in years. We are still in desperate need of more programmers to write new software for any and all of the different types of Amiga experiences. The Amiga experience means so many different things to so many people still, I don't see how anyone can think that the Amiga is dead.
It is definitely different than it once was, but I would not call it dead. Choose one or more part of the existing Amiga experience that still interests you and become involved. Recruit new users or programmers, learn to program yourself and write new software, or port existing software to any, or all of the different Amiga experience flavors, set up a user group to rekindle the Amiga spirit in your area, etc.
There are dozens of ways to continue to support and enjoy the Amiga, you just need to decide which way you would enjoy and pursue it. The Amiga is what you make of it. If you are sad and disappointed that the Amiga did not fulfill it's ultimate possibilities and was driven into obscurity by the people who mismanaged it, get over it and enjoy what is left. The past is ancient history and can't be changed. Live for today and enjoy what you can. If part of that is any of the Amiga experiences, great. If it is not fun any more, maybe it is time to give it a break and come back to it later. (I am not promoting people leaving the Amiga, but some people probably should from the looks of a lot of the complaining and fighting that goes on in many of the forum sites).
I am enjoying all of my Amiga experiences and looking forward to the future and where it will lead. I am also trying to become more active and pro-active in promoting and helping what is left of the Amiga community.
If you are still waiting for Amiga to make a comeback and become a mainstream competitor again, then yes, I agree that you are only dreaming. Come back to reality and enjoy what we do have right now.
Funny that you should reference Battlestar Galactica. I just started watching the whole series remake again on DVD. It was one of the best SciFi series ever made IMHO and I think it broke a lot of new ground in it's creation and style. It had comedy and drama in good proportions and the acting was pretty good for a TV series that lasted 4 seasons (really 5 or 6, because they only aired half a season during a couple of the years it was broadcast). So, give a Frak and start enjoying your Amiga (what ever flavor they might be) again.
Edit: Totally agree with Slayer that wishing for the Amiga to repeat the 5 times better at 1/3 the price, before anything can be considered an Amiga again is just plain stupid. If that is really your opinion and attitude, it is time to step away for a while and re-asses your life and priorities maybe. Again, computing on any of the Amiga experiences today is what YOU make of it. YOU can make it good, or you can complain and bemoan what "Should Have Been". Choose to do something that will make it better than it is and you will feel more fulfilled than the choice to complain and wish for something that does not exist. I am also a realist and don't claim that any of the Amiga experiences are more than they actually are. I point out their short-comings and try to support people that are working to improve the experience with new software and improved OS work. I hope to do more in the future, but do what I can in the present. Do what you can and you will feel better about it. More people working on the problems will speed a resolution, but won't magically restore the Amiga to it's former glory.
