This Backpack is perfect. I don't need so much space in my backpack. It fits my laptop (15.4"), my kindle DX and a book and all other compartments are for my accesories. It is perfect for what I needed. I previously had a Belkin Core Laptop Backpack (Pitch Black/Soft Gray) fits up to 15.6-Inch laptops but it needed a little extra space to hold one book to be the perfect backpack. The Solo backpack is perfect for my needs.
I am happy with my choice and would buy it again, it has been several months since I bought it and I have no complain.. having an special compartment for laptop makes it easy to reach it when you are in a hurry (for instance, making a line in the airport).. i would definitely recommend it
