Seems like the world is trending away from people owning this kind of hardware. As a consumer I want to be as hands off as possible. Not sure I want to deal with the overhead of putting a server in my house.
Now my phone, laptop, boxee, etc can all sync from that central store and pull data from it on the fly, at 802.11n or gigE speeds. So I'm not burning battery life waiting on Comcast and burning through my wired and wireless data caps.
As long as consumer internet is slow and battery life limited, and particularly as data caps become increasingly common, there's going to be a market opportunity for a local media store that can be used to sync your various devices.
Interesting username then...
But I think that if it is an appliance rather than a server -- this thing is great.
