If I didn't have a CSPPC, I probably wouldn't still be using an Amiga. I don't really think a stock Amiga can be given a place in the modern computing world - 00s. An expanded/upgraded Amiga, though, is a different story. It may not be able to run much of anything a PC can, and it creates a challenge to find ways to get the output generated by an Amiga into the mainstream, but it's certainly possible.
Just about any time I sit down to do a project, I first try to work out how the Amiga can get it done. Most of the time I don't even involve the PC. The Amiga has just enough to make it work. On the occasions the Amiga can't cope, I start with the PC. And almost invariably, frustration sets in because the PC wants to fight the way I work. I still get work done, but without that warm fuzzy feeling, y'know?
