I bought this bag prior to my holiday to Bali, and that was a perfect bag. I could use it as normal backpack or if my shoulder hurts (weight...) then I can roll it out. The sealed bearing wheels are the same type as rolling skates. Neat. The rubber is not so hard so it absorbs vibration from rough road surface. This bag comes with small notebook (12" monitor). You could put your notebook into front pocket. The backpack shoulder could be slipped behind the padding when you want to roll the bag so it wont get dirty. The padding is so thick and comfortable. I have to rearrange the inside padding so I could put inside 20D with grip because on the middle there is a channel for the extendable tube system. The channel height is perfect dimension for 20D and BG-E2 till bottom of lens.
