I received an airport Express as a gift and am questioning if I should keep it or exchange it for an ABS Extreme. My current set up is as follows: an ABS (Graphite original version, serves as main entry point), and an airport Express for AirTunes in the living room. My goal is to replace the Graphite ABS with newer technology. My options: 1. Exchange the Express for the Extreme (paying the difference) and replacing the Graphite ABS with the Extreme. 2. Keep the Express and replace the Graphite ABS with the Express. If I do keep the Express and eliminate the Graphite ABS: 1. Can I use it as a wireless printer connection as well as a main source for internet at the same time? 2. Is there any real reason why I might want the Extreme instead? Looks to me like you get, with the exception of the extra ethernet port, more lights, which I do like but can live without. Thanks!
