1. It's the first MorphOS demo, so worth mentioning

2. MOS is amiga-compatible/like, this demo is for morphOS. MOS is part of the amiga world / community. We didn't say the demo itself is amiga compatible. (but it works on an amiga with morphOS)
3. I guess they could do that
4. This is just to show that MOS is being chosen by more and more people as demos / games / apps are being developed for it. Of course AOS4 version of those software wouldn't be a problem I think.
There's no reason why this kind of news would annoy people

Remember : new things being developed for Pegasos mean new things which could be easily adapted for A1.
