I am a bit confused. Do the statistics represents people who still use their Amiga today or people who still own an Amiga but do not use it?
I still own an Amiga 4000, but I haven't used it for a long time. The thing is, I use WinUAE which uses Workbench from my Amiga 4000 drive. So, I agree with Minuous.
This is a an interesting project though, because it can grow bigger.
