I just got my very first Mac, a new 13" aluminum Macbook, and now it's time to go bag shopping. I've read through a whole bunch of threads on this topic, but none of them were quite as specific as what I'm looking for. I'm looking for a shoulder bag, and the focus is more on productivity and functionality than fashion. One case that caught my eye was the "Brenthaven ProLite I Case for 13-inch MacBook": First and foremost, I need a case with the most protection and security possible. Ideally the case would fit the laptop perfectly, so it's comfortably suspended in a nice padded space. I'm the type of guy that tries to protect my laptop from getting even a single scratch, even though I know it's bound to happen eventually. I'd also like the bag to have room for a few accessories (like the power adaptor and a monitor adaptor) and some small books/paper. The Brenthaven ProLite I is the sort of thing I'm looking for. It looks like the Macbook fits snugly inside, it has little file-folder type things on the back for papers/books, and a pouch on the front for cables and pens and stuff. I'm not specifically against messenger bags either, but based on what I've seen so far they lack the space that these shoulder bags tend to have. I don't really want any of those sleeves either. I'd rather have just one case I can put everything in before I leave, and take everything out at my destination. Does anyone know of or recommend any other cases with this style? Anyone have any thoughts about the ProLite I? Thanks.
