I use both Windows and Mac OSX at BV Software. I really like somethings about each operating system and since we make web based apps we need to test them on both platforms. Tonight my 2 1/2 year old son showed me why a trashcan beats an orb.

I had my laptop booted into Vista and Gideon was "helping me" finish up some email messages. Click here, click there, window opens, etc. Not a peep out of him.  When I was finished I rebooted into OSX because I remembered that he liked Photobooth and making silly pictures.

OSX was on screen and in less than 2 seconds Gideon promptly pointed out "Ooo, Trashcan, Oooo Book." That is great UI design. My 2 year old instantly recognized a trash can and that the Address Book program looked like a book. He can't read but he understood perfectly. 

He never said one peep about the Windows "orb" that represent the Vista start menu.
