I've been very pleased with this bag.  I originally planned to use it as a shell with padded inserts for my DSLR camera, but it didn't quite fit as I'd hoped.  So instead it's turned into a general purpose satchel and I'm using it a lot. It holds my Transformer tablet with keyboard doc in a sleeve, 2 small books, snacks, wallet, keys, pens, iPod and point & shoot camera.  A standard sized notebook will fit, as will a small folding umbrella.  The material is soft but seems sturdy. The strap is comfortable.  The length adjustment slips a bit, but not so much that the periodic adjustments bother me.
