Some people apparently slide laptops/magazines/small stuff into that area, too.

I'd also highly recommend getting the Absolute Strap-- it's worth the money and lives up to the hype. It's worth it even for non-Bihn bags.

Re the Red Oxx XS Aviator-- it's a great little bag and excellently priced, but there's no strap. (There are various threads on modifying it to add a shoulder strap, but it's not standard.) For that reason, it's not so practical for me unless I'm balancing it on a large bag. But you can fit an incredibly amount of stuff into it since it's an open space.
