I think It does add alot to a machine like that. Me? I think mac hardware is very nice but since I've run linux for many years, osx is just not that exciting to me, so I never bought a mac. I always thought they were way to expensive. On the used market though... 50-100$ is not bad for something to play with.
I keep saying I will buy a g4 mac for this, but haven't yet. If anyone has one cheap, pm me, especially if you'd like to trade for some amiga stuff. I have an amigamaniac svideo adapter, and svideo to vga adapter,an a500 brick power supply, and a bunch of aminet cdroms, maybe some other odds and ends.
