I also insta-backed this bag (and all the accessory bags)! I'm a bag addict, and Peak Design makes some of my favorites.
I'm pretty excited about the travel backpack. I love traveling with just a backpack, but still haven't found the perfect bag for it.
The bag that's come closest so far and that I've been using for the last few years is the Tom Bihn Brain Bag. It's 95% perfect, but I find it inconvenient to have to open one of the two main compartments to get to my laptop, and I wish the accessory pockets offered better internal organization.
