Well endowed would be a good description to start, but there are a few things missing. Let's get those out of the way first. This Epson does not offer 3D capabilities. While there's great interest in the classroom for 3D, use is still very limited. Still, if 3D is in your future, Epson does not have an ultra short throw projector for you. Epson, I should mention, does offer their passive 3D W16SK projector, which would be worth a close look if 3D is something you need/want.
And it relies on pens for its interactive functions, you can't just use your finger tip. OK, finger tip control is a new feature out there, I"m not sure if there are even a handful of projectors that can do at the screen touch control at this time. I know Epson's slightly more expensive Brightlink 595Wi is touch or pen (up to 8 folks collaborating at once), but as this publishes, the 595Wi still hasn't shipped.
OK, there's also no zoom lens, but, ultra short throw projectors don't have zoom lenses. They technically have no use for them. Epson does give this projector digital zoom, however, a nice feature, if a bit different. The digital zoom works well, and there's a photo showing the effect - with the zoom being controlled by Pen (or you can use the menus).
What else doesn't it have? Well, it runs on conventional lamps, not a 20,000 hour plus digital light source such as led projectors or laser projectors. For most, though, that's just fine. With the Epson lamps costing education users only $79, and lasting a claimed 4000 to 6000 hours depending on full or Eco mode, the cost to keep in lamps is only a few hundred dollars to get to that 20,000 hour mark. Considering that solid state light engines add roughly $500 to $2000 to a projector's cost, those provide the convenience of not having to change a lamp every few years, but lack the strong value proposition of a well priced lamp based projector. Further, technology may make all these projectors obsolete if not used 40+ hours a week, before anyone gets near 10,000 hours, let alone 20,000. Business users, you'll be paying about $200 each per lamp, but if you are using this projector even 20 hours a week, it will be 4 years before its time to change the lamp for the first time (if only using full power).
Two pens are included, and, of course, a remote control. This projector is built to interface - with the world. there are iOS and Android iPresentation apps from Epson to allow you to use your iPad or favorite other mobile device to present or to interact. (Mimio also offers up an App.) And the projector can present off of USB or Wifi, as well as HDMI, component video, composite, S-video and analog computer. Of note is that one of the two HDMI ports supports MHL (discussed in special features section). With MHL you can interface with a variety of mobile devices which include Roku sticks, a few Android tablets, some cameras and a lot more coming. The last of these three images shows the projector with the cable cover installed.
