I think this subject needs to be narrowed down a bit. So far, people seem to be interested in the maturity of the technology (which is rather ironic), but not much has been said about usability, capability, overall features, or just the fun factor. The A1000 had a solid OS architecture for its day, but I don't think a lot of people bought them so they could program libraries all day. ;-)
Also, I wonder how many people have actually used both AmigaOS 4 and MorphOS so a fair comparrison can be made.
Me, I finally bought a Mac mini (in transit) to accompany my Windows and Linux systems. I'm afraid the word "Amiga" is merely a memory.
