Yep, it's a nostalgia-driven hobby, no more, no less...
Back in the Amiga heyday the whole personal computing landscape was evolving - and the Amiga was at the top of the heap for a shrot time, but thing have changed.
These days computers are more of an appliance, in the same was as a microwave or toaster. In the good old days it was all about pushing the boundaries, the huge leaps from 8-bit micros to 16-bit machines.
There were the first few steps from the blocky, limited colour graphics and 'beep-beep' sounds to photo-realistic GFX and 16-bit CD-quality sound. At around the time the Amiga died, Windows was beginning to reach the technological plateau that we've now reached.
But, back in the late 1980's it was like a brave new world. Each new machine brought with it genuine, significant differences and technological leaps. These days there are still improvements to hardware and capabilities, but it's nothing like the advances we saw back then...
It was great...
Mike.
