So now that I have an iPad (64/3G), and travel a lot... I have a question: I want to go on the road armed only with said iPad sans macbook. If I'm at a hotel with only an ethernet cable, and don't want to use my 3G (as in international), can I just bring an AirPort Express and hook it to the cable to create a wifi network? Never used the AirPort Express, so... Thanks for any thoughts!
