For what it's worth, I like the bevel, because (probably due to the darkness of the colors involved) it somehow manages to be almost invisible at default zoom - if I just go to http://www.yahoo.com and look at the logo, even on a Retina display, it seems almost flat, with just a hint of varying color to spice it up. It's only when I look closely that the true depth is revealed. This adds visual interest... or I may just be blind. :)
