The value proposition in terms of picture quality, brightness, warranty and more is better than most of the competition. In other words, if your requirements are met by the Viewsonic, it's likely one of the best values out there. While we're talking value proposition, this Viewsonic, I believe has the best warranty of any of these small LED projectors. Not only do you get a three year warranty when most of the competition is serving up one year, or two, but it comes with a first year rapid replacement program. Score a big one for "peace of mind".
Certainly the PLED-W800 is extremely portable. Yet it's got enough brightness to be a serious presenting projector for those sticking to small to medium sized audiences. Not enough "horsepower" to tackle a room with 200, but with decent lighting control, 50 people should work well.
At home it should prove to be a very capable gaming projector, even for very serious gamers. And it will work very nicely though no match for a home "theater" projector, for your home entertainment, be it sports, general HDTV or movie viewing. On that note, find some bigger sound if you are watching most movies.
Bring it home and it should be very good gaming projector - even for serious gamers. And it will work nicely as a home entertainment projector. No, its picture quality isn't up to a good $1500+ home theater projector, but for "home entertainment" translating to less critical viewing, in a less ideal room, it will perform.
All considered, the PLED-W800 is impressive in its performance for such a small, lightweight and mobile projector. It's flexible - home, business, education, gaming, and even digital signage, thanks to its 30,000 hour light source! If you don't need something it lacks (such as 3D or higher native resolution), it's definitely one of the best of these LED projectors in the class.
