Great - BUT -it seems Optoma are PC friendly and ignore mac users.

Summary: Great little projector. Very versatile for what it is - plays off my computer, my phone, the sd card and more. I have Apple computer and an iPhone. I had to buy a hundred $s worth of cables and adapters - big draw back for me - plus pixel display ratio and between PK320 and my 17" macbook pro seems...
Summary: This is a really handy little device. For a small item, it produces a surprisingly clear picture. A couple things I would like to see improved....the directions, which were minimal; and it would be helpful if the lights remained lit on top of the unit when it is turned on.
Cool by itself, but clunky when you attach it's various cables

Summary: Because the projector is so small, it actually becomes quite unwieldy when you attach the VGA cable and the power cable and a tripod to it. All those extra connections pulling it various directions make it quite unbalanced. It's much sleeker if you use it standalone and battery powered.
Summary: Easy to use once you decide on how to connect to your device. Very portable but make sure you carry the right connectors. It displayed nicely on a variety of surfaces but the lumens are few so take into account the ambient lighting.
Summary: We bought the Optoma PK301 in April of 2011 as a solution to wanting a big screen but not wanting to leave burglar bait in our vacation home. We were more-than-most-happy with its performance until it malfunctioned this August, just four months out of warranty.
Summary: Personal Experience I am yet to find a video format that this projector will play despite its advertising. Not any of my standard MP4's and not avi. So basically it doesn't work in stand alone mode unless you just want to show slides - which is pretty useless for a pico.
Summary: Although it's very portable, this projector was not bright or clear enough to demonstrate our software, which is what it was purchased for, so I had to return it and replace it with another unit.
