Michael Lopp wrote about moving from a messenger bag to a backpack. This is a fantastic look at the thought behind choosing a great bag. I love Tom Bihn’s products and the [Ristretto that I use](http://brooksreview.net/2011/02/new-bag/), but I think I am going to give a backpack a try after reading this.
The primary problems with the Ristretto are:
1. It doesn’t scale well.
2. Nothing in it every feels truly secure. (I have watched things slide out of it during take-off.)
Here’s to backpacks? We’ll see.
