My only real complaint is the lack of line in and line out ports. This severely limits the rooms I can put the device into as compared to the older SX10. The next step up is a significant cost difference that will deter several of my customers from using it.

Beyond that, Ciscos lack of willingness to provide a wall mount for the touch 10 has prevented me from using it in many scenarios where I ended up being forced to use a crestron touch panel instead.
