I was looking at the Chromes but they don`t appear to be very comfortable or ergonomic. The new Booq bags apparently are very comfortable but their looks are a bit wonky to me. I`m not crazy about the Timbuks but that may be where I`m heading. I think the most important qualities for me is that the bag not be too bulky (while still having space for a 13 inch Macbook, some accessories and some magazines or a book or two) and be able to take some weight off through well-conceived ergonomics.
