I use my 3 pieces of real Amiga hardware (acelerated A1200 and 600 and a CD32 with MPEG) mostly for retrogaming and retroprogramming fun. And I like it that way.
In what future is concerned, I think AROS for intel machines has a chance. I'm using it now to work with something I can really call "Amiga" with the power of a 2 GHz Pentium 4 machine (my old PC). It's still too young, but I can see a potential there that somehow I miss in the other alternatives!
