I was on the apple store today and saw an ad for STM bags, which I had never heard of before. This bag particularly caught my attention: http://store.apple.com/1-800-MY-APP...2lR2ovuyNJ0PSKWCt5/22.214.171.124.126.96.36.199.188.8.131.52.1 Not only does it look pretty nice, but it has plenty of nice features. I really like the rain guard. As a college student I often walk through rain. I would also need room for textbooks, pens, calculator, beverages, etc. But I am also looking for something comfortable and somewhat compact. I see a lot of laptop backpacks that look just huge. Another concern of mine are backpacks that put the laptop directly on your back, as opposed to in the middle of the backpack. I could be wrong but it seems the curve of your back might put stress on the laptop and the screen. Any recommendations are appreciated.
