I was catching up to my pod casts, and at 1hr 24min 11sec Leo Laporte (while talking about packing for his trip to China) mentioned he was using a Tom Bihn TriStar. He indicated that he was able to pack 1 weeks worth of clothes, and his laptop into the bag. He brought up the packing cubes, and indicated he wished he'd had the bag for his trip to Canada. He also brought up RedOx, but I won't hold that against him.
I'm sure he'll be reviewing it on one of his other shows the Daily GizWiz.
Most of the show is about Mac stuff, so If you're into it and haven't yet listened, the link is here.
