Because of the laptop/ipad support, the 7 was a little more rigid than the 10. I like the way the 10 forms to my body. I did like that it was slightly wider and shorter though - easier to get more stuff in and out fast. However, it was basically too similar to the 10 and I didn't feel like selling the 10 to recover some of the cost of the 7 (cuz I'm lazy). I think the UD 35 is better for laptop support since the opening is a little larger than that on the 7. Plus, I like to be able to use the Tom Bihn Absolute Strap on a "heavy" bag which I can on the UD bags but not on the Retro bags.
