I bought this for my astronomy club that uses it for presentations to public, schools, scouts. I had previous experience with a couple of older models. This one really is dramatically improved in several ways. Ability to use with HDMI of course as well as USB and SVGA connections. While previous projectors also had keystone corrections, this version adds an additional feature that lets you tilt the image side to side which is a neat feature. The remote has a few tricks of its own...the best is you can turn on a pointer on the screen to point out things. You can leave your red dot pointer home. It is 2800 lumens and plenty bright and does not need a long cool off period before completely shutting down. The 3CCD is one of the factors that give much better color perfomance and the lens is sharper than I remember on older projectors. The USB ability to use flash drives, etc. may not be completely useable for your purposes as it only works with some image types and not Power Point. This last is expected as you really need to use a tablet or laptop with PP or its free reader. I wasn't expecting this to have a speaker but it does although of course not going to fill a large room. It is OK for very small groups.
It comes with a nylon case for the projector and a small amount of room is provided in the case for some cords but it is on the small side...would have likd a bit larger case to hold more of the cables but his isn't a big deal. We take good care of our equipment but it might be worthwhile getting a heavier duty hard case for transportation if you are a "road warrior" type of user. I recommend Pelican brand cases.
Bottom line for a computer projector is the image quality. We need very high image quality to show our astronomical images at there best...this one does it. It is HD at 740p which is sufficient for our purposes. At this point no one makes a 1080p HD projector at this price and quality point. I figure that will be the model upgrade down the road but hopefully it will keep the form factor of this model and not the bloated home theater projectors that cost a LOT more money. The auto keystone adjustment and level control are convenient...makes for a fast setup. This one has been in use now for about 2 years and is ofen used outdoors at dusk to project astronomy presetations on the side of our observatory. Even at dusk it is more than bright enough to be seen clearly. There are some newer models that incorporate wireless but I have seen reviews that mention these are not that great as only a limited number of file types will work with them. Frankly you are better off using a wired connection.
