the miniaturization of technology be amazing . with ipod and cell phone and netbook I have always have way to show neat stuff , but generally one at a time . nobody like to squint over a tiny screen or deal with view angle . something small and battery power that I can just stow in my bag and project on any wall would be pretty great . unfortunately , this just do that and do not quite seem to be as magical as the pr make it out to be . as far as control and circuit logic go , it be pretty plain . just a stand-by screen wait for input , volume up and down , mute , battery check , and off . no color adjustment . no 16:9 \/ 4:3 toggle . no high-power mode when plug through ac . I know it be small , but even a simple color adjustment could maximize the range of non-ideal surface you can confidently project onto . the image itself be fair quality ... even though this 2010 model have double the brightness of the earlier 3M model , you still really can not consider use this in a light room . that `` whether you be in a cafe . . or conference room '' really be a bit of a stretch since the cafe be not go to let you turn out the light . one real annoying bit about the display be the rainbow effect that drive I crazy from early dlp television . newer revision be fast enough to minimize it , but the red\/green\/blue flicker be quite obvious with this . I would say that rule out most movement-heavy video source , relegate it to the world of Powerpoints and camera shot . for those thing it should do fine : the standby screen give a nice big `` 3M '' logo in the center and you could use that for a focus reference . as the machine stay on and heat up , though , it seem to lose focus a bit and it then become a little more difficult to readjust because the focus dial be now hot . last part about the image quality : you should know it be a 800x600 display , so , even though you could , in theory , hook up a 1080i or 1280x960 wxga source , it be all gonna get scale down to 800x600 anyway . ye shall find no forgiveness for small font . Audio be another let down . the volume adjust only have 4 level so there be not too much control over it . and even at it be highest it barely exceed the noise of the cooling fan . while it be nice it have a headphone port for more substantial audio setup , I would not see why you would route it through the projector unless you be force to -lrb- by use hdmus or a dedicated ipod cable -rrb- . now the stuff that do not matter quite so much . it come with a lot of goody . it come with a flex minus tripod with a standard mount post , which mean not only can you mount the projector on any standard tripod , you can also put anything on this mini-tripod . it also have a fold-down kickstand to raise it , so , it seem like a duplicated accessory . you get ton of plug adapter which be nice , a composite cable with gender adapter for each cable , and a VGA cable with audio tail . the connection be flexible but I much would have rather have real port on the side . there be room enough for composite , component , hdmus , and a 1:1 ipod cable . it would not be neat and it would be scatter all around each edge , but at least I would not have to carry a additional bushel of cable for device I might want to plug in . round up the accessory be a little carry case that fit it just perfectly . unfortunately , with the extra stuff you 'll have to carry around , the utility of a carry case that just fit the projector be a bit silly . I would have be fine with just a snug little lens cap . I think they include all this stuff because after be a little disappointed with what you get you might not want to throw more money at it for adapter and cable . look , I understand it be a pocket projector , but really I do not think the technology be there yet . seem the biggest limit factor of the technology be the battery with a leisurely 2800 mAh . if it simply have more juice then they can crank up the brightness , color cycling frequency -lrb- less rainbow -rrb- , and audio . it take 3 hour to charge but last only 2 while operational . all this put together a ho-hum product that will put off my fantasy of a impromptu drive-in movie date on the side of a tractor trailer in a parking lot for perhaps another 5 year .
