Well Amiga, Paula, Agnes all sounded like names of girls, girlfriends etc. That's appealing to most men;-)
Now Petunia, Buster and Gary, I don't know what these people were thinking:-) But seriously for a fast 68K emulator I would expect a name like cyclone, raging bull, blitzkrieg, Tommy Gun, Naplam etc, not the name of a fragile flower:-D
