Summary: The MP410 is excellent for video and stills. My experience is limited to input from micro SD only, have not gotten the USB or internal memory to work. However, I have run a few .mp4 videos and a number of high res. stills. The cool side is that the HDMI input is very smooth from my iPhone 4S....making this little jewel very useful. With the HDMI setup, I am able to skim off the audio with a HDMI2HDMI + Audio [also from Amazon].
Summary: Because of an ordering snafu, for about a week I had both this projector and the Dell M110. I'm hear to tell you that they are the exact same project except for the Dell being about $100 cheaper.
Summary: I'll admit, I got this particular projector with the hopes of using it as an outdoor projector. In that sense, I've been fairly disappointed in it. It isn't that the projector isn't bright and powerful, it is that the speaker is completely dreadful. Worse yet is that there is no way to plug speakers into the unit to get a better and louder sound. This makes using it for entertainment or video presentations nearly useless.
