The main reason I use my Airport Express on the road is the added layer of security when using hotel internet. It's not perfect, but it's supposed to encrypt everything you send and receive over its wifi. I'm sure it can be hacked, but it's better than nothing at all. Even if a hotel has wifi, I connect the Airport Express to the room's wired internet and create my own little wifi network and use it instead of the room's wifi. Works great.
