I thought I would join in on this Xbox 360 support train.
I use Xbox 360s as extenders for my WMC Server and they work great. I can get to Plex and Netflix through the Xbox, and the WAF is high. I don’t have to switch sources, and I use 1 remote.
There are not too many other ways to integrate Cable Live TV, Neftflix and Plex into one box, and it would be a darn shame if the Plex Devs abandon what might be the most elegant media solution available.
Stop it with the support evey latest gimmick in the search for more money, and get behind some of the most stable and well vetted platforms out there like Xbox 360.
If this is a problem with what Microsoft lets developers do on their platform, come out and say that. Ignoring your existing users is just bad business.
