I have been using a Domke F-802 to carry a load of gear that can vary from notebook computer (MacBook Air 13"), book and/or magazines, lunch, Zojirushi vacuum bottle and a sometimes small SLR or RF camera.  That's a lot of stuff, and truth be told it's heavy when loaded and I don't carry that much very often.

So I was looking for something smaller that I could carry every day, something that would carry lunch, the coffee bottle, pens, etc., and on rare occasion my MBA.

This bag fits the bill pretty well.  The MBA =barely= fits.  If I have an SD card insert, it doesn't fit; with the tiny Logitech universal receiver in a USB port it's tight.

The pockets, including the inner zippered sleeve, are plentiful enough and a variety of sizes so as to be quite practical.

Other than wishing that the bag was maybe 1/2" wider, the only thing I don't like is the arrangement of the strap securing the front flap.  First off, it seems to me that it is upside down; the receiving clasp is attached by a very short strap to the bag's flap, while the long portion of the strap is attached to the bottom of the bag.  I find this clumsy.

Secondly, I don't really care for the clasp.  Even though it's plastic, it seems sturdy enough.  But the buckle is the kind that requires you to pinch prongs, which usually requires two hands to insert or remove the prongs from the other end.  The clasp on the Domke is a MUCH better design, being a hook and ring design.  And it's metal, to boot.

This bag is no Domke in design, materials or construction, but neither is it priced like a Domke.  It is pretty much what I expected, and I expect it to provide decent service.
