Just wondering if there are any plans in the works for the production of a messenger style bag with a larger capacity than the ID (Empire Builder size?). I just purchased a size 5 Brain Cell for my Ibook but am hesitant to purchase the ID because of its limited capacity. I'm a grad student and need to be carrying around more than just my laptop and some accessories. I love the capacity of the Empire Builder but I'm really not interested in a briefcase (I bike to work) or a traditional pack like the Brain Bag. I know Tom mentioned something about the production of a bag meeting these criteria on these forums earlier this year - has anything developed? If possible, I would like to purchase from Tom Bihn again as I am very impressed by the quality and always appreciate American craftmanship. Thanks in advance.
