Since the Macbook Airs should be released soon, I wanted to know other people's opinion on protective sleeves and the best way to go about protecting an 11" MBA. I'm planning on purchasing a MBA when they are released. I would have to carry it in a backpack, which really worries me. I am planning on getting this discontinued STM Rogue Small from Amazon since it conceals the laptop and suspends it from the ground, better protecting it from impact. http://www.amazon.com/STM-DP-0920-1...r_1_2?ie=UTF8&s=apparel&qid=1308686651&sr=8-2 The problem is, I don't know which sleeve I should use along with the backpack. I have narrowed it down to 3 sleeves. The Booq Viper Hard Case http://www.amazon.com/Booq-Viper-11...480E/ref=sr_1_2?ie=UTF8&qid=1308686379&sr=8-2 The Hard Candy Bubble Sleeve http://www.amazon.com/Hard-Candy-Ca...1?ie=UTF8&s=electronics&qid=1308686793&sr=1-1 The G-Form Sleeve http://g-form.com/product/extreme-sleeve-for-laptops/ What do you guys think about these three and which one should I get? Again, I'm looking for the most protection. Thanks in advance.
