Designers are doing miracles these days. It was very nice of them to create a netbook backpack from which no one can get anything when it sits on your back. This particular model has a zipper on the backside, and it can be opened only when the owner takes it off his shoulders. Great for metro, buses, suburban trains, well, for any crazy city.
Update: After an extensive discussion with our readers we decided to add that while this backpack cannot protect your purse properly, it is still very good for keeping your laptop safe.
