The signals for me:
When Amiga offer me a machine that is as fast and as powerful as a modern day PC. I don't believe in buying another machine which is heaps slower then my Pentium rig.
It should have a user friendly operating system that is similar but different to Windows, and good security and internet features.
But, it all should be cheaper, and this would also attract my patronage.
These threads may be flights of fancy, but I don't think people who create these threads, or who believe that the Amiga can be resurrected, should be criticised.
