My backpack finally bit the dust and I needed another one-- I hate change and I hate looking for the perfect backpack
This one is not perfect but very close -- I have been using it for about a week and it is working out just fine
It keeps my little netbook safe and my precious kindle too.  There are places and zippers to keep all my stuff where I can find it quick.
It is not too big.  I thought I might need the big backpack but knew - since I am not a large person - it might be too big.  The size it just right--if anything I think another small pocket on the outside - for my phone would be great.  There is just one and it is a tight fit for an iphone.  Of course there are a lot of places and holders inside the pack.
I love the water bottle holder - many bags have done away with this and this was a deal breaker. This one has two.  I put water in one side and the other will fit a small umbrella if you are so inclined.
For the price and free shipping it is a great deal and a nice back pack.
