The request was for a solution to mirror the desktop of any PC, Mac, iOS, Android device without having to have a special software or download, etc. Prijector seems to fit the bill at a much lower price than Qomo or Vivitek. Not that price is the driving factor. The Prijector also has some additional features that could be useful like available "apps" for most major VC systems, etc.

I may get our Vivitek rep to chime in on the Novopro as it looks pretty good as well. I am sure they all work similarly. It is just a question of which will be the least headache to setup and use. Remember, this is for "Dummies", not integrators to use. :)
