Plus, the Integrated AIGLX based 3D Desktop is wayyyyy too cool. U'll start making even MacOS guys jealous :)
Hmm... the point of jealousy would be in terms of it looking ``wayyyyy too cool" AND being GPL through and through. Let's face it Apple rules when it comes to building interfaces, Aqua(on Mac OS X) is one of the most crisp and elegant looking UI's out there, moreover they take the same care and precision in making their widget sets !!! Pity they don't seem to have any inclination to release that bit under GPL.
An interesting article on the same :
