The Sanyo PLC-WL2503 isn’t the first whiteboard-less whiteboard solution we’ve seen — in fact multi-surface projector interaction dates back at least as far as 2007 . As for a projector with built-in interactive capabilities, well, Epson’s BrightLink 450Wi has been on the job since last year, albeit at a much higher price: the Epson projector costs $2,200 while this Sanyo comes in at about $500 less. Both tout short-range projection: the BrightLink provides 80-inch displays from two feet, while the PLC-WL2503 requires at least 34 inches to do the same. They pack identical WXGA 1280×800 resolution and 2500 lumens of brightness, and they both use IR pens to communicate with front-facing cameras built into the projector for multi-surface interactivity. Really, the only thing separating these two on paper is price. If the BrightLink is just too rich for your blood, and you can wait a little while longer, the Sanyo PLC-WL2503 can have you writing on walls by the end of January.
