The Big Board
Tired of annoying shadows interrupting your projector-based lesson? Samsung’s E-board Touch 650TS-2 can help with a classroom-sized touch monitor. With a 65-inch display, the E-Board Touch is large enough for the whole class to see and can rival classroom projectors with brighter, sharper images. It uses tiny cameras mounted at each corner to interpret finger movements so you don’t even have to touch the screen to get a response. Because it has an estimated lifespan of 50,000 hours – more than 30 years of typical classroom use – you’ll never have to buy or change a projector lamp ever again. On the downside, it costs $7,952.
