I'm thinking of buying one and the two different models seem to be differently priced, though the only apparent difference is the color. In the case of the translucent red one, I'm worried that the clear housing looks like something that you could get fingerprints on, like the clear and black Apple Pro Mice. I HATE fingerprints on electronics with a passion, and am currently leaning towards the green one, though it's a bit more expensive. Can anyone with one of these mice comment on the figerprintyness factor? Alternatively, I've heard bad things about the Copperhead's Mac compatability--apparently, USB Overdrive doesn't work with it. Can anyone confirm this, because if it's not true, then I'm rushing out and buying it instead of the Diamondback right away.
