Hello,
I guess you have to ask yourself, do you think that if Genesi had made an 'Operating System' (Morph XP) that looked and worked exactly like Windows XP and ran all Windows software or an 'Operating System' (Morph Mac) that looked and worked exactly like Mac OS and ran all Mac OS software that a court of law wouldn't think this was infringing on the rights of Microsoft or Apple? I think a court might even side with Microsoft on that. Just because Amiga Inc. is a lot smaller and most people have never heard of Amiga OS doesn't make it anymore legal to do the above. I think there is a reason no other company makes a ?Windows Compatible? OS.
Why do you think M$ didn't tried to sue Lindows about its compatibility with Windows and rather just about his name? (and even with that he lost

)
I help you, simply because they'd have lost and they know that. Even if Lindows look a bit like Windows and run a lot of Windows apps.
I?m sure some company would love to sell a product for half the price of Windows XP that looks and feels exactly like Windows and runs the entire existing catalog of Microsoft Windows software, but I think they know they would probably have no legal ground to stand on.
Well in fact it exists already

It doesn't look like Win XP but more like Win 2k but not exactly. It can run Win apps Btw and I mention it just before

Yes I'm speaking of Lindows

And for the legal aspect see my answer above

Btw MorphOS don't look exactly like AmigaOS 3.x. It has similarities bu it also has lot of differencies and new stuffs.
Additionally, the interface is themable if you want to make it look exactly like AmigaOS you can, just like you can do it on Win XP or MacOS X using themes.
But MorphOS has its own look & feel even if an Amiga user will indeed recognize some similarities with AmigaOS, it has not the exact same look & feel. In fact its look is just more modern

Regards
