I've been switching away from WMC, not because I don't like it (it's actually a product MS has done a really good job on), but because it doesn't work as seamlessly with the videos I watch (mkv and iso files). When I was living in the UK and had a DVB tuner, I used it as a PVR and, since I had a smaller TV, the videos I downloaded were avi's and worked fine. But Microsoft would have to find a way to sell a box that works with the different types of TV reception - satellite, cable, or freeview in the UK, and that wouldn't be easy. (and it would be just as big of a pain in the US where they would be able to sell the most units), so I can understand why they haven't. Still, it is strange that nobody else has really tried to sell hardware specific to WMC.
