Mean terp though Purple? Not yet, but me and 4 friends of mine witness sloppiness of terp though Purple! Mind you one of my friend actively work for Sorenson, and the rest including myself was work for Sorenson. I wish I had videotaped it and show here. That guy should be fired!
I found a big problem with SmartVP. I had a great chat with one of AD members here recently and was talking about remote control on smartVP. We both know what RF and IR is. Since SmartVP use RF, while Sorenson use IR, Sorenson made right decision using IR not RF. Purple, well, ahem since they can have 5 separate account on single SmartVP which mean it won't matter if using RF however a SERIOUS big BUT if a person have smartVP, got new roommate that have smartVP too. Both of them WILL have problem with remote control, why? If roommate press button on smartVP, both of his smartVP and his roommate SmartVP WILL respond same time EVEN if is in different room. Not good!
Sorenson VP, if VP in two different rooms, no problem with remote control, that because Sorenson remote control use IR not RF. IR can't though wall, RF can though walls.
Purple did big improvement from MVP to SmartVP, but still long way to go.
