With a throw ratio of about 1.2:1 this is close to ideal for our application. My wife wants to use it for displaying sewing patterns (PDF) and either cutting material directly or tracing to paper. To that end, one of the possibilities is to use it in a vertical orientation and display directly on the cutting table. Can someone please comment on whether it is OK to use in this way (will it mess with the cooling). It is dead easy to connect by airplay to an iPhone, iPad and MacBook Pro. The fact that it can run on its battery and not need to be tethered to any cable at all is just the ducks guts. This is an excellent, very portable projector. If I were to criticise anything, the focus knob is a little fiddly and the lens cover hangs in the projected beam. We hold it with an elastic band but a better solution would be handy. Overall very happy.
