Admit it, how many people saw this thread, were using the new XP Luna interface, but then saw all the "cool" people in this thread who think the new interface sucks, then changed it, and then posted that they use the classic interface. I see 29 people voted they use the XP interface, and not too many have said anything. Come on, if you use it, just say it.
Personally, I use a modified version of the XP Luna silver interface (gasp!). Why? Because I like it, and I'm not ashamed to admit it, and I don't define my manliness by my OS interface. I have made some changes to the default, I have a blue start button instead of green, I use the quick launch bar, I use detail view exclusively for explorer, I have shrunk the minimize, restore, and close buttons down to a really small size, and I use the drop down menu control panel instead of opening it in a new window.
