Thanks to TB and myself, I now own a Co-Pilot as my daily school bag (I'm a HS teacher who is trying to go paperless with an iPad and a few letter size papers ONLY!)... and I also plan to use it as a trip bag that will fit under the seat in airplanes :) I really wanted to find the perfect bag for those two uses. I have some comments for possible improvements of course, which I'll write about later on.
For now, just test driving it, and enjoying my new Co-Pilot... it actually seats in my car passenger seat instead of my trunk or back seat... :)
In the pictures you will also see a short strap matching the interior colour and a small clear pouch, a cork wallet and in the middle compartment, my Starbucks cup fits perfectly! Amazing!
