Silly application, but well worth the 99 bucks for me... I travel a lot and many of the hotels I stay at don't have wireless. I get anchored to the desk with the RJ45 cable. So, I'm using the Aiport Express to create a secure private wireless network in my hotel room. I guess I could just have bought a really long RJ45 network cable. But who wants to travel with a 25' cable.
