(More customer reviews)Currently, I am a student teacher at a high school that is not equipped with much in the way of high technology. I have struggled with the fact that the most advanced permanent piece of technology in the classroom was a slide projector (yes, SLIDES) that I had to dig out of my parents' garage. Coming right out of the university, I was used to making presentations utilizing the Internet and Powerpoint. It had been my hope that with my first teacher paycheck (a year later, that is) I would be able to purchase a multimedia projector for classroom use. To my great surprise, my parents were able to pick up the PowerLite S4 at an Office Depot for a very good price, and gave it to me as a gift for Christmas. Being a student teacher, I am forced to move around from class to class. This is where I have found the S4 to be very able. The S4 is, as the name implies, very light. If my hands were a big larger, I would easily be able to pick it up with one hand and have no problems. While it is certainly not the highest powered projector on the market today, it certainly throws out quite a bright image. The color is vibrant and can be seen when all the light banks are on in the classroom. I prefer to have the lights off, obviously, but lights on does not destroy the image. The S4 offers many different inputs, but the projector supplies only one with the product. Another feature that I enjoy is the time it takes for cool down. As a teacher on the go, I need to be packed up and ready to move on in about 5 minutes. The S4 cools down fast, which is definitely attractive. The sliding door for the lens is very nice as well. One of the only negative experiences I've had with this projector is that I have found that the projector must be hooked up to the computer before the computer is turned on. Once I figured that out, I have not had any trouble. For teachers and presenters on the go, I highly recommend this projector.
