Epson also offers the Powerlite 1725, which has all the features of the 1735, but with traditional XGA (1024 X 768) resolution.
Also in Epson's 17xx series projectors, are the Powerlite 1730W, essentially the same as the 1735W, but without the wireless networking, and the 1720, a non-wireless version of the 1725. If one looks at the current Epson 17xx series, they will find that all four models offer 3000 lumens of brightness. The older 17xx projectors these replace also consisted of XGA and WXGA projectors, some with wireless, but with lumen ratings from 2200 to 2700 lumens. Another key difference, is that the older ones offered a pr etty much industry standard 2000 hours of operation in with lamp on full power, and 3000 hours on low power. The Powerlite 1735W, and the other new models all claim 3000 hours in full power, and 4000 in low power mode, which definitely reduces the cost of ownership.
The 1735W’s light weight and size (and this is true of the other projectors in the series) makes it extremely portable (11.2" wide, 7.9" front to back, and 2.8" high - and that includes its feet). In terms of footprint that's about the same as a standard sheet of paper. It could easily fit under an airplane seat along with your laptop, but it is also set up for easy fixed installation in a conference room. The image here, shows a pen, and also the USB key sitting on top of the 1735W, to give you size perspective.
