UPDATE 2.11.2009: Yes, this bag is awesome. I just took it on the plane as my carry on. In it was: my 13" MacBook, its charger, 2 books, my headphones (which are the big clunky DJ ones), travel wallet, bag of Reese's, gloves, earmuffs, a balled up sweatshirt... etc. with room to spare. You get the picture. It's small enough to serve as a carry on, but can fit so much. And the straps are sturdy, I didn't think they would break off or that the bottom was gonna drop out from all the crap I threw in there. Great bag, 5 stars!

This bag is great, it's really well made. Not cheap quality at all.

It's big enough to fit my 13' MacBook along with books, my camera, bunch of other stuff so I look forward to using it as a carry on.

It's nicely lined with airplane-print, and the zippers are sturdy and have Pan-Am logo charms on the ends. The strap loops are big enough for me to carry this over my shoulder.  I am really happy with the size and quality of this bag and would recommend it to anyone.
