It's true that reliability is pretty good. But it still isn't as reliable as many other consumer devices. Until it is I agree that GUI work should wait. Some reliability problems I see: 1) Occasional brief freezes during playback. Probably when playing back HD and recording two HD programs. (HR20-700 with external RAID1) Suspect it takes just one I/O error and retry/recovery to cause this. Not enough buffering in my opinion. 2) New software update ALWAYS fails to see external drive on reboots. ALWAYS have to power off everything and restart to fix. Don't care that they don't support external drive - when they have TB+ storage in RAID1 internal then they have a right to ignore this problem. 3) Depending on the release, the over-the-air tuners get lost after a couple of weeks requiring a reboot. I've had the HR20-700 since it was first available. A couple of different external RAID enclosures and drives. The above problems have persisted for YEARS through many software updates. A GUI not being pretty enough is irrelevant to me. Don't follow the Microsoft approach to reality.
