I've got the Lowepro Compu Rover AW. I would NOT recommend it. It's a pain in the butt.
By the time it's got all the gear in it it's very heavy and cumbersome, even though it's in the spec's for airline travel I find some planes it doesn't fit. This is without a tripod on it as well.
These days I travel with a not very laptop looking laptop bag and a separate camera bag and find this setup much more user friendly.
Good luck with finding something to do all
Actually I also have a
CompuRover AW and so far am relatively pleased with it. The tripod harness works quite well and centers the tripod on the front. In the bottom one can fit a larger camera (although I don't now if one can fit a D3/1D in it, a 40D with battery grip and 17-85 lens fits also quite nizely) and a larger zoom lens and one to two (or even three, depending on the size) additional lenses. The laptop compartment should house even a 17" MacBook Pro (although I mainly have rain trousers and a fleece jacket in it while hiking) is well padded an on the rear of the bag.
The top comparment has some storage area for storage cards and can hold everything you need for a one day hiking trip. You can also open the bottom to get to the camera compartement which is quite handy if you want to carry a larger tele lens which otherwise wouldn't fit in the camera compartement.
The carrying system is ok. A dedicated hiking backpack is better but it's ok. I used it during a trip to Scotland and it was comftable enough if all belts are closed.
The downside is it is somewhat heavy (weighs about 2.5kg empty) so you might run in weight carrying restricting for onboard luggage (or do it the Reichman way and put some lenses in your pockets) and it can be somewhat larger than officially allowed sizewise for carry on luggage. So far I managed to fit it in all overhead compartements and the displays (don't now the correcht Englis word. The things where you can test if you carry on luggage meets the size restrictions).
So, the question is, what do you want to use it for? I needed one for day hikes with enough space to fit a camera with up to three lenses while also being able to hold everything else (water, food, rain clothing, warm clothing, the things you (might (e. g. temperature drop)) need (or should have) i a different compartement while hiking (ok, usually one can arrange pure camera backpacks such as the Kiboko to get something similar but I prefer to keep these compartements separated). For this the CompuRover AW had been the best compromise, but it is a compromise, to be sure, but a rahter good one in my opinion. For longer distances I use normal hiking backpacks because of their better carrying systems and put the camera in bag around my waist and the lenses in pouches in the backback and my tripod where normally the hiking sticks would be fastened to the bag.
For every other occasion bags such as the Kiboko might fit your needs better. So far, I haven't found the perfect one yet (and most probably never will (hmm, maybe I should enter the Kata Design Contest ).
