I haven't seen a review for this bag here on POTN, so I decided to write one of my own.
I've owned this bag for about a year, I bought it because my Lowepro SlingShot 200 AW does not travel well. It does not hold a laptop, or a book, and it does not leave much room for the usual travel documents. So I aimed at the CompuRover and picked one up off of ebay.
Funny story, it was a second hand bag, shipped from China, wrapped in a garbage bag with a shipping label. Chinese customs "inspected" the package with a razor blade, so the first thing I had to do was patch it up. Luckily the damage was mostly cosmetic.
So here I am, and I've been traveling with this bag as much as I can since I bought it. It has a lot of space for all of my camera gear, laptop, a book, iPod, noise-canceling headphones and everything else I like to take with me in a carry-on bag. Because it's a large bag, when fully loaded it can get heavy. But the straps, padding and belt make the weight managable and comfortable.
It will fit in an overhead bin without effort, but if you end up on one of those flights where overhead storage is limited for some reason, I've managed to fit the monstrous bag beneath the seat in front of me fully loaded. The down side is that you'll need to be a yoga master to get something out while you are in your seat.
I've also had occasion to go hiking with this bag near Lake Tahoe. While it's designed to hold a lot of things you wouldn't take hiking, it still makes a comfortable backpack with nothing but your camera gear inside.
Please excuse the poor photography, a full gallery with notes is available here.
