Bought one of these at Costco a few years ago and I love it. Very durable and comfortable and still looks new. Use it daily going to/from the office (far better than a laptop case) and also pack it for trips, business and personal, instead of checking in bags. Can get a week's worth of fresh clothes in it, packed right. And the padding on the back has a gap around the spine for ventilation so you keep cooler.
The regular Costco price is actually very good, but they tend to run coupons on this about once a year - about $7 off. That's a fantastic deal if you can wait (not ran this year so far).
