Victorinox - Architecture Classic collection
I wanted something slim and lightweight since I'd be lugging around a 17" MacBookPro.
I found this one on Amazon which has proven ideal:
Victorinox - Architecture Classic collection
Built with ballistic nylon, it's tough and the nylon doesn't wear.
Although this picture shows a Treo here, this pouch fits my iPhone snuggly. The interior of this pocket is soft and seems to clean the display every time I slip it in.
The photo shows a 15" in there for some reason, but the 17" is a perfect fit.
The power brick fits perfectly in that square pouch on the left.
There's room for a couple of Sharpies, business cards, etc.
There are also a few hidden pouches in and around the bag.
The strap is very comfortable. I used to have a leather Armani bag for my old 15" and it always hurt my shoulder. This one was built for comfort. Somehow, I barely feel the weight of the laptop, perhaps because the center of gravity is taken into consideration here, while my Armani bag hung lower.
I'd definitely recommend it.
You can get it here.. It's on sale now.
