Hello all! So I just bought a new 17'' mbp and I am looking for the ultimate MBP backpack. I came down to two options and I am really in two minds. 1) Booq Mamba Shift L 2) Tom Bihn Smart Alec My criteria: 1) Functional and durable. 2) Stylish but unpretentious design-wise. 3) Allows not only laptop storage but also enough room for holding few basic clothes/books/food when traveling. 4) Ratio Quality/Price. They both seem to have about 27 litres volume. Currently I am in Germany and shipping the Smart Alec from Seattle would cost me a bit more than getting a Mamba. What would you get? Thank you.
