I think with the Zero series Oakley really missed the mark in recent years. They had something really special with the hard lines and unique lense shapes. The whole organic flowing lines works fine for o-matter X-metal etc, but the Zero line looked so unique and out of this world. Now they just look... Ugly.
Exhibit A:
This is just my opinion, but I don't know of anyone that would say the new Zeros are as nice as the old ones.
