I am setting up a network with a macbook air, mac mini, network music player and a ps3. Today I'm using my old Airport express (802.11g), but when my mac mini arrives this week I'm not quite sure if the speed will be enough for Time Machine, Torrents, PS3 downloads and sending music to my network player. The audio port on my airport express won't be needed, as I'm using my network player for music. Anybody has any experience with this? Should I A: just keep my AE and leave it at that, running everything on 802.11g? B: Buy a cheap router and hook up the network player, PS3 and mac mini through cable while using AE for the macbook air? C: Buy an Airport extreme (802.11n) and sell my old Airport express. Cost is an important issue here, but so is stability and aesthetics - a cable free solution would be preferable, but not if it's not stable at least 99,5% of the time.
