I just received the bag today, and I'm very pleased with it. I plan to use it to consolidate my lunch, paperwork, and other odds and ends for taking to work.

Here are a few things I noticed about the bag that potential buyers might want to be aware of:

 - I was surprised by the size--it is BIG! The dimensions Amazon lists are not accurate. The width across is about 21", but I like having plenty of room so I'm okay with it. I can fit my 17" laptop in the main compartment, just not in the laptop sleeve--but I knew this beforehand. The side bottle pockets easily fit a 24 oz. reusable water bottle.

 - The bag seems to be made of a high-quality material that should be easy to wipe clean if it gets dirty. The material does not feel cheap to me, as one reviewer seemed to think.

- I would prefer if the exterior pocket were horizontal instead of vertical to allow easier access to items, but I can live with that.

All in all, a great bag. As long as you're aware of the things I mentioned, you'll be pleased with your purchase.

UPDATE: I decided that the bag is just a little too bulky to take back and forth to work every day, so I have returned it to look for something more compact. However, I still think it's a great bag!
