Thanks for this article. I'm a guy and just bought my first 'bag', a Citynews Briefcase. It's Togo leather, with a Sombrero II handles, and Sombrero II reinforcement on the bottom. I'm worried about the weight of a 15" Macbook Pro (4lbs) stretching out the leather. Any thoughts on whether this is too much weight for a bag? I'm assuming since it was built as a briefcase it's designed for more weight, than say a Birkin, but I don't want to ruin this bag.
