So I just bought a 13" MBA, and I have my iPad that I'd love to carry in the same bag. I'm in Grad school, so I'm carrying at least 1 ~1000 page book with me, and maybe a small notebook as well. I have a Jansport Right Pack (http://www.jansport.com/js_product_detail.php?cid=1&pid=TYP7) which I have had for about 10 years and has been amazing. But I'm looking for something new. I've looked at the Incase Compact (http://store.apple.com/us/product/H...fnode=MTY1NDA2Ng&mco=MTc5NzIzMzQ&s=topSellers) and the Thule Crossover (http://store.apple.com/us/product/H...fnode=MTY1NDA2Ng&mco=MTcxNjEzNzk&s=topSellers). Does anyone have any experience with these? Or any other advice for a good backpack, or maybe a messenger bag? I've been scouring the internet, doing major MRoogles, but can't find anything really informative.
