So long, but I'd replaced you already
I've used WMC as my main setup for most of the last 8 years. It had several things going for it - it was pretty reliable when it came to recordings, very easy to use for the non-PC literate and I had a hefty htpc running it and serving streams via DVBLink.
However, I recently replaced the htpc with a Chromebox running Openelec/Kodi, and tvheadend doing the backend, and I'm really happy. Kodi's PVR functionality is not exactly intuitive in places (Add Timer??) but it's a cheap, almost silent and lightweight solution that works really well. Though having all the USB tuners plugged into a hub behind the chromebox isn't quite as attractive...
