I own a silver HD5 and while my buttons haven't cracked (I only use the remote!) I noticed something else. The colour of the USB cover is considerably different from the rest of the "silver plastic" on the top side of the unit. The front side of the cover (not so much the top side) is a lot darker, almost like the dark silver on the top side of the black HD5. It's really noticeable if you look at the front of the unit and rather annoying for unit that's as expensive as the HD5.
