Overall, the 826W is a solid, low cost solution for the classroom or conference room requiring network capability. As a portable projector, it's of a size and weight typical of the lower cost portables. At seven pounds, it's about twice the weight of some smaller projectors that are similarly bright, it's also a good size or two larger. All considered, it may not be the first choice for someone who travels with a projector every day, but it's just fine for occasional trips, or moving from room to room. The Epson Powerlite 826W displays photos and videos with a sharp picture and good color balance. Once you add in the long lamp life, Epson’s excellent Road Service replacement plan and technical support, it’s a hard package to beat. Long term cost of operation is a big issue for schools. With a lamp life roughly double the average projector, the cost savings there may offset the extra time needed for those occasional filter cleaning/replacements. Most DLP projectors, by comparsion, do not have a filter to change, but their lamps typically aren't rated as long a life, and typically are higher wattage, plus DLP projectors normally use more electricity (let's say 20-25%).
The relatively powerful 10 watt speaker is a real plus, and money saver in a classroom environment, as most projectors come up short on sound, requiring additional expense for outboard speakers, wiring, etc.
