This is a great little unit that I use for business presentations. Now I no longer have to deal with the companies equipment making set up and take down a lot quicker. Overall I am extremely happy with the unit. Sure there are brighter ones available but not with a battery pack and the portability at this price point. The few things I would improve would be the touch panel, little bit cumbersome at times and the focus, just make it have a bit more resistance to make focusing easier. If you are thinking to buy a pico, dont think twice about the Samsung.
