As I'm waiting for my Macbook, I can't help but look at various accessories.
I've come across the Brenthaven website, they seem to make really nice laptop bags.

One of the models caught my attention, the Sling I. I had a sling bag for my photohraphy equipment and quite liked how it could be slipped on/off so fast. So i'm very interested in the Brenthaven version for laptops.

I'm wondering if the extra storage is enough however. If there's people who own that bag, i'd like to know just how much stuff you can carry in the bag.

Can it hold the power supply cables in addition to a compact camera, an iPod, a pack of cigarettes and stuff like that?

Also, are these sold in stores anywhere, or only online?
