Purple better change from RF to IR on their remote control. Using RF is bad idea IMHO. Also, navigation on SmartVP is somewhat confusing, worse than Sorenson, and I could be biased because I know how Sorenson VP works inside and out, however I usually acts as if I am idiot customer, that is how I determine the quality of interface. I learn alot from many customers on daily basis on how they navigate the interface, especially low function, and elder Deaf customers. I feel bad for them getting real confused where it is actually simple.
Same happened to my wife, I asked her to call my dad to arrange pick up our two sons though my smartphone. She kept asking me how I make call. My response was, whats functional equilvent? Call the way hearing people would call same way. She was like what? What? Where? I said look at phone icon, just hit that. she said no, I need Sorenson. I said LISTEN, just do it. She pressed that phone icon, it works and made call. This is the reason why I hate the idea of "Functionality equilvent" which is truly very confused for Deaf people at best.
I noticed video is somewhat better with Purple to purple, and Purple to Z, but not Sorenson. I do know why, and Sorenson STILL has best video CODEC period.
