I previously asked a question here about fitting several articles in a bag, and I got such useful answers, I thought I'd try again. So...
I have a Large Cafe Bag which is very useful. In it I carry my iPad (in Waterfield Travel Express for iPad case), a Moleskine, a Kindle, glasses, some pens, a spiral notebook and a textbook. If I don't have to carry lunch, this is the bag I'll always take.
Now I'm looking for a briefcase-style bag that will carry all of the above plus lunch. Lunch is usually a sandwich or two and a Tupperware container about the size of a Clear Quarter Packing Cube. Maybe a banana and/or an orange.
So...I'm looking for the smallest briefcase-style bag that will carry all that. I think that would be either the ID or the Zephyr. Note: I won't always have time to pack cleverly , so this bag would have to something that could fit all this stuff when packed hastily (i.e., I'm just throwing stuff in there...).
