I went into and apple shop today and talked to them. Brought one home.
Right now Blondie is beaming across the house!!!!
The device should be able to link to my existing WIFI modem which is a netgear 834. Thus I should be able to stream music and surf at the same time as the PC or Ipod is only using one wifi connection. However, it has proved to be a real head ache. I think the Apple Airport and netgear device are not fully compatible. So for now the express is "stand Alone" so I can connect to the internet or the stereo. I'm not giving up yet!!!
