I agree with all my fellow bag-obsessives: this seemed perfect when I bought my first one. I had the first version of this bag for three months -- and the zipper failed on the side laptop compartment pocket. The replaced it per guarantee with the update, and I am thrilled to see that now I can access the laptop compartment from inside the bag, without ever messing with the side zipper. Awesome! I have no comment on the quality of these zippers, and will never have to, because I will never use that side zipper again! It's brand new and I trust it will wear like crazy for years. Lack of a water bottle holder was my only quibble with the original design - and now I have two. I am one happy bag-obsessive weirdo now.
