We just had one installed by a contractor a couple weeks ago in a conference room. The touch sensors on these are very particular when it comes to the size whiteboard/screen/wall you project on because it has to be to a certain degree level and board bezels can be only so thick. If you are installing it yourself, do your homework. After you get the hardware installed, the software calibration takes about 20-30 minutes and involves multiple adjustments to the sensor and mount. The projector is a short throw not an ultra short so there will still be some shadow while you are writing and the image quality is visibly less sharp toward the bottom of the image. An annoying aspect for us was the department wanted flexibility to bring in visitor laptops to connect and use with it. They didn't share this with the contractor when they were specifying parts. So now I am having to go back and get the parts to make a VGA and USB drop and get them to buy a GoWire so they don't have to install Smart software/drivers every time they bring in a new laptop. If this sounds familiar, then I recommend you make sure they purchase the LightRaise 60wi2 because it comes with the GoWire which will save you about $500 if you had to purchase it separately.
