Also, a "simple" Amiga program defeats the purpose of argument here. Not to mention, getting things to work on Amiga isn't always a walk in the park.
I disagree. Most "simple" Amiga program work straight from where you unarchive them. I've found very few "simple" Windows programs that don't require you to "install" them. That's one of the things I LOVE about the Amiga. If I want to try out a program, I can usually unarchive it RAM: and run it. If I don't like it, the next time I boot my computer it won't be there, none of it, no left over junk.

True. I've have install scripts fail on me on the Amiga. But if a Windows install fails on you, you're pretty much screwed. If an Amiga install fails, it's a LOT easier to figure out how to install it manually. (Especially with tools like SnoopDOS that let you see where programs are trying to find files)
