Teacher: Now, understand the problem? Solve this instance: This is not my first laptop backpack. But it is the best! I bought this for a new laptop and a long trip to Russia. I needed a very protective pack, with lots of pockets for all my extra gadgets (external speakers, wireless mouse, etc.) I'd need for staying at a series of hotels with no conveniences for a long period of time and a lot of long flights, many with *no* entertainment (Aeroflot!) I also wanted secure but accessible pockets for passports, etc. Since I'd have it with me pretty constantly it also had to be comfortable. Lastly, while roomy, it needed to fit under airplane seats. ALL of theses conditions were met with flying colors! It also turned out the build quality was excellent. Oh, one last positive. The backpack easily \"butterflies\" open at airport security, and very quickly comes back together after the scan. The fact that it laid flat in the scan prevented me from delays. With all the extra batteries, speakers, headphones etc. I envisioned getting manually inspected. Never happened!
