Count me in for a black or titanium grey one with a clear lid, maybe even 2 in both colors. Would be awesome if the clear lid fit snuggly on the box, kind of like the the plastic lids do on tupperware. Or better yet, if there could be some sort of latching mechanism to ensure teh lid stays closed when traveling.
If we have to have an aluminum lid then I would definitely like it to have some sort of Geekhack logo.
