Ok, but what is that? Seriously... Desktop computers have been trying to come up with an aesthetic, intuitive GUI for decades now. I'm not sure that any of them are necessarily "trying" to look like each other any more... They just all look like each other because that's what people except.
So, without an idea of what exactly Linux should look like, it kind of hard to imagine.
Maybe I'm looking for the best thing of each viewed world, (by me)...
If I want/need OS X, I must buy an iPhone, but I want a platform wide open like maemo with a lot of apps, using an interesting and amazing interface like Aqua, (it doesn't mean that maemo's UI is not good), but, your answers can be studied like an interesting social behaviour between advanced users, noobs and geeks. All of you are right, even me... in our very own worlds.
