Just recently, I had been thinking of switching from a backpack to a messenger bag for carrying all of my tech gear. Don't get me wrong, my backpack has served me well over the years; in and out of airports, all over the U.S. It's a Swiss Gear Synergy, and I truly love it. However, I'm not afraid to admit, it's a little large; it holds all of my stuff, with quite a bit of room to spare. A couple of weeks ago I saw a neat messenger bag, and it got me to thinking. The bag I saw wasn't too big, yet still seemed to have a lot of space to carry plenty of gear. As I am frequently on a plane, I was looking for something that fits under the seat nicely, something my backpack does occasionally (depends on the plane.)
Yesterday, while reading Phandroid, I saw a review for a Powerbag. While they make backpack and slings, I thought their messenger bag was pretty cool. Here's Phandroid's review. I would like to actually see one of these in a store somewhere so that I can check the size and weight; but it really looks cool. The added bonus is that you can charge the phone, etc.
