Hoi - it depends on how and above all where you use this projector - i.e. whether you take it mobile to customers or stationary in your premises. - BUT- The lumen power is not really great and the resolution is not suitable for presentations (WVGA...). today we are behind vHD on the screens of the devices and produce content for it accordingly - downscaling usually doesn't work well). If you want to set up something for your rooms, take a simple, cheap and flat TFT for the wall and either a Barco (or something similar) to present on it. If it has to be mobile, take something with more luminosity and resolution... my2cents
