Introducing the Crumpler Shrinkle. It’s a wacky name for a camera/laptop combo backpack, but it’s also an unconventional bag. It has some sense of design and style (when it comes to camera bags, at least), and it seems very reliable and feature-packed. Of course, I don’t know any of this first-hand, as mine still hasn’t shipped yet, but this hard-to-find bag from Australia gets glowing reviews (from people who ditched their LowePro Trekkers and other similar bags for this) in many forums.
Just for-what-it’s-worth: I bought mine from Set Shop, a place here in the US who actually stock Crumplers.
