I made this a couple days ago
That was fun!
I use my Amiga as my main graphics editing platform (ImageFX, Aladdin4d, DPaint, etc.).
Otherwise, for MIDI stuff (Bars & Pipes). There is no better MIDI sequencer.
I have several hardware Amigas that need repair. I'm using a WinUAE setup right now that just functions so smoothly and feels so real that I sometimes forget I'm not working on a "real" Amiga (it's a real Amiga to me and I get a lot done with it).
