Well, this emblem of the ProtoToasters have been etched on every piece of Mac hardware I've ever owned. MacBooks, iPhones, iPods. You name it I etched it.
Reminds me of a very cool part of my life when I feel in love with technology.
It's not for me.... I'd rather have mine etch-free.
I'd recommend adding a few more to make it more symmetrical. It seems a little off-balanced. I think it'll look a lot better if you add some to the other side of the Apple....
