I still think OSX is better than Windows ;) oh and I'm pretty sure the "lights" (the white little glowing dot under the icon) is already a part of 10.6. I also haven't checked out the preview yet.

Using much of the same reasoning you use E.G. Safari finally has full screen browsing....Windows 7 finally has full indexed search!, or way back in the day, Windows 95 finally has a start menu...I could really go on...
