I've seen them in a couple of local boutiques. They're vegan (no leather), and every bag that I've looked at has nice organization. They have pockets for PDAs/cell phones, and magnetic key fobs so that you don't have to search for your keys! Why other companies don't offer the key fob is beyond me. The only reason that I haven't bought one is that I like smooshy leather bags.
I always think their designs are great. If you want a vegan bag and don't want to pay Stella McCartney prices they're a good option.
