Thanks for all your comments -- this post has helped me understand the different options for running Amiga software than on my A3000s.
For me, a lot of what I like about the amigas is their ability to be very efficient in much the same way as Freebsd is efficient. I also like the gui that amiga provides, which FreeBSD and linux do not rpovide me.
I don't know what to get next and am still thinking. The underlying hardware is not as important to me as the classic is no longer being produced, logic has me realise that my A3000 wont last forever. So, I need new hardware because the price of adding to my A3000 is quite considerable.
Yes, intel is not great, but with the processing power, bus width changes and other technologies, it is much faster -- the problem today with microsft, while they have made great strides, is far too slow and heavy: it still can't properly do the following functions:
1) process swtich between hihg load and light load processes: unix has perfected this over the past 40 years.
2) Paging to disk is so poorly handled that the whole system becomes sluggish.
For these two reason, I am looking for an alternative. Amiga still is a logical step for me, what I need isa platform I can use. Morph OS sounds good as does Aros, but my systems are intel now

I guess I am still looking for a perfect solution.
