Document: or Android devices (again phones, tablets, whatever devices the application would install on) is incredibly easy. The technology is similar to the fruity company's AirPlay technology, though in the context of the iProjection application the feature set is much more limited. When using the iProjection application (at least at the time this review was written and submitted) a user of the application would be restricted to specific document types, photos, or internet (browsing) projection.

You will need to output audio to an external receiver or speaker setup in order to hear anything from your source. I understand, however, that projectors are treated like computer monitors in this regard-- Speakers are not the focus or point of such a device. Still, I'd have liked more connections to pass the audio through from HDMI.
You turn on the pointer with a single button click on the remote but to move the pointer around on the screen you have to use the arrow keys on the remote. While that may be fine for some presentations it makes for a time-consuming and tedious process if you want to point out several things on different parts of a slide.
You have to choose a virtual display (no explanation is given) and then restart your computer. Once the computer was reset and the Epson network software started, the wireless projector was easily found and once the security settings were set, the screen of the computer was being wirelessly projected.I can see the wireless connection being very convenient since the computer is no longer tethered to the computer and so the person controlling the presentation doesn't need to sit near the projector nor are long cords required.
You can use multiple connections at the same time and toggle between them. You can also use the split screen mode to show two images side by side, one from each connection. I connected the projector to several different laptops including a netbook and a 7 year old laptop without problem.
You can purchase the $99 wireless key adapter, but you don't need it, at least with a Mac, it's a piece of cake to connect it. However, it needs to take over your wifi to connect to the projector, so keep in mind, if you need internet, you'll need to have the laptop plugged in via ethernet.Brightness is great, clarity and color even in a well-lit room. Overall, very pleased.
Yes, a screen makes it look better, but white walls work well, and the blackout cloth needed to make your own screen is readily available in any fabric store.Final verdict: Excellent for entertainment purposes. Highly recommended. Five stars!
With the downloaded software, it is streaming wireless contents from iMac to the projector.Fan noise:By switching to ECO mode (dimmer but less fan noise), fan noise reduced from 40db to 30 db. I was a bit bothered by the fan noise on regular mode.Lamp:TheEpson ELPLP65 Replacement Lamp - DP9608costs 177$ (at the time this review was written) at Amazon.The black case with an Epson logo that came with it has multi-compartment and is padded for protection.
