I am going to buy either an airport extreme or airport express. It will be used only for Internet access for my ipad. I did a google search and found a lot of information on the airport extreme, and it should meet my needs fine. Because of cost and portability, I would prefer the airport express, but I have not been been able to find anything on it, especially as to performance (e.g. how well it penetrates walls in a house). Does anyone know of any reviews or other performance information on the airport express? BTW, I will probably buy direct from Apple refurbished. http://store.apple.com/us/browse/home/specialdeals/mac/mac_accessories Thanks!
