I am looking for a bag for my MBA 13". I really want the Incase 13" bag. (They call it a sleeve?) http://www.amazon.com/Incase-CL57482-weather-resistant-Macbook/dp/B0043NTOKC/ref=sr_1_11?ie=UTF8&qid=1330220440&sr=8-11 . There are 2 front pockets, you can put your charger in one of them, and put an adapter or external hard drive in the other, very convenient. $60 for this is way overpriced. Where I can get this for cheaper, or something very similar? Note: I have seen the bag/sleeve thread, no match for what I want.
