I be fortunate enough to be able to test this product for the Vine program . the 3M Pocket Projector MPro150 be a product that be useful , as my job frequently require presentation without there always be projector readily available . I be happy to take a look at the mpro150 , to check out its different capability and see what it could do . in term of the quality of the image , I have to say that the projector look great project against a screen or a plain wall . the box say that it work at up to 50 foot away from the surface be project onto , and while I do not test it at that great a distance , I get a great look picture at all the different distance upon which I try it . as far as ease of operation be concern , the unit be superb . the menu have some easily recognizable pictogram , and navigation be extremely simple . I have little problem go through Excel and PDF file , as well as the more vanilla powerpoint and text file . good stuff . connect to other device be pretty simple . it really be plug-and-play with the pc , and the iPod\/iPhone hook-up work quite well in be able to play music directly from the phone -lrb- though not , say , picture from the phone -rrb- . the smart card work well with the unit 's file system , and I can not get over the projector be able to actually hold presentation , plus video and all the rest . very cool . overall , this device do everything that I could possibly have expect it to do . I would give it a solid five star .
