Currently, I'm using a Thule Crossover backpack to carry my MacBook and personal items/paperwork. One of the things I don't like about the bag is that there's barely any padding on shoulder straps. I'm thinking of selling the Thule on eBay/Craigslist and get a Booq Mamba daypack. I like the simplicity of the bag (never really cared for a bunch of pockets on Thule), and judging from the photos I've seen online it seems like the shoulder straps have enough padding. Any thoughts?
