You can only stream through Google properties though. Can't even stream from a local PC. So even if you don't care, it's kinda funny. You have to stream things over the internet all the time.
The hardcore might be using things like BitPerfect and using their own DAC/AMP combos or whatever.
Sure, not saying that part isn't stupid, it is. But a device that lets you stream music to it _and_ offer decent amplification at less-than-Sonos prices is a pretty good idea.
If the Q was $100 and let you stream in a fashion similar to AirPlay (ie, any media on an android device), it would be unstoppable.
