Hi guys, I am thinking of getting an Airport Express to replace my house's main network router right now. However, I am not sure if the Express version will provide all the functionality I need. I want to limit my budget right now, so I would like to stick with an Express if I can (I mean what additional functionality would I need from the Extreme?). I would like to place my the new Airport Express in our main entertainment area so that it will stream airtunes over to my receiver via optical out, and stream HD video through the ethernet to my PS3 (so the media will be streamed from my Mac Mini one room away via Wireless N). The wireless signal from the Airport Express will also need to be strong enough for a laptop in the 1st floor of the building (the AE will be on the second floor) as well as my Mac Mini. What do you guys think? Would the Express work for me?
