I always wanted a Timbuk2 bag but was worried about the structure of the bag and the protection it would afford my laptop. After a recent visit to the Apple store I found the Finder Messenger and it was a perfect fit for my needs. The padded sleeve protects my 13" MBP and iPad and still has enough room for chargers, a small moleskine notebook, pens, business cards, some folders of important files and even my Patagonia down sweater vest(when packed down in its own pocket). The wide shoulder strap is comfortable and feels great when slung across my body. I would recommend this bag for anyone looking for a "casual" and very functional and durable messenger bag
Sizing is perfect for 13" Macbook Pro. Macbook/iPad sleeve is heartier than it looks in the picture, and is secured to the back of the bag with velco, and also with a heavy strap that runs along the front to secure it in place. Even with some jostling around, it holds everything right in place. The organizer pockets are inside the main body pocket and are fairly standard issue. There are two big pockets big/deep enough for a big calculator and a smaller pocket big enough for a wallet and three pockets sized for pens or the like... Great bag, great price, you'll love it.
