I'm looking at buying an Airport express. I currently have a wireless router that works fine, but lacks two functions that the Airport has. First, I can't currently connect a printer or hard drive to my router. Second, Airport supports AirTunes, which would be super convenient. So my question for anyone that owns one is: could I connect both a printer AND a hard drive using a USB hub, or does the router support only one device at a time? Also, if anyone has any other options for what I'm trying to accomplish, that would be appreciated.
