Just received the black amazon cover in the mail today for kindle 2 for my husband's kindle. First thing I noticed is it felt slightly lighter than the one I had. I weighed it. It weighs 5.8 ounces as apposed to 6.25 ounces for mine which is not a huge amount but it does feel a bit lighter in the hands. Weird. It kind of looked like the charcoal grey interior was a little thinner inside so maybe that's the difference. Still just as protective though.
