I have an itch to explore into this area again... And this time it feels like WHS has matured enough and with the recent changes on my home server (SBS2003) that I no longer need to host Exchange at home, so the home network can be a little less forgiving.
Anyhow, we have plan to get AppleTV, however am not too sure if it will play nice with WHS for media streaming.
And if not, what's the next best recommendation? PopCornHour A-110? PS3?
