Simple question, what do you generally prefer applications to be in? Do you think they're better with a skin, or do you think they're better just using the default OS style. (Games only count if they're windowed.)
Examples:
Skin
No Skin
No real reason for asking this, I've just always personally found that No Skin was always better, because I like when all my stuff matches. Skinned applications (For example, the new AIM which I refuse to use) just annoy the hell out of me.
System native.
Also with Active System Box you can mix system native with style and create a very good looking application and keeping it native.
Also Vista is ugly with a skin or without it! <_<
