Hereafter are the listed factors:
1. Doesn't work with universal remotes
2. It's louder than stand-alones
3. Interface isn't as easy to use
4. You have an older AV receiver and need multichannel analog outputs
5. You want to save money/trees
6. I need to see my receiver light up and say "Dolby TrueHD"
7. Jack of all trades, master of none
For noise originating from the fan-based cooling system as well as the high power consumption does not really make it the best device for customer willing to watch BD HD movies while sitting in their living room. Audio HD output restrictions might also be a rather negative point too.
