Which case/sleeve would you rather have for your Macbook Air? Has anybody seen/used both of these and can comment on them? I really don't care for using the laptop while in the BookBook so that is one aspect of it that I do not need to really consider. I love the look of both of these sleeves but I am looking for a sleeve that doesn't add a ton of bulkiness to the Air (main reason I bought the Air in the first place). The Knomo is a bit more expensive but it is really tempting me with it's good looks and sleek design. So which one would you prefer? I know people's opinions vary on stuff like this, but I'll ask anyway. Thanks! Also, if anyone has the Knomo, could you please post a picture? Thanks!
