My point exactly. This is a broad definition, not equal to "receiver/decoder box connected to some content source." So no, such solutions will never replace HTPCs, just make the market more focused (read: even smaller
Your comment is a bit blurry. I know we are basically in agreement, but there are semantic differences.
It sounds like you're saying that the conventional definition of HTPC as a PC that connects directly to the TV (acting as PVR, tuner, etc) is too narrow, and you don.t accept it. Well, whether you accept it or not, that is the definition of HTPC.
To speak more broadly, there's no stepping back from the digital home with multiple computers. We invariably run networks, have multiple computers, and share files among them. Those files end up being displayed as video on the TV, and music on the stereo. But a PC no longer has to be directly connected to the TV (or stereo) do this. With smart TVs, they can interact with the network w/o any need for interface devices... and for non-smart TVs, those interfaces devices can be smart <$200 boxes instead of PCs.
You can still fiddle all you want with specialized programs for all kinds of media manipulations from your PCs -- but they don't have to be connected to the TV or in the same room.
