I'll keep this short. Last year we considered projectors in this class primarily as ultra short throw projectors, some were fully interactive like this Epson, others weren't, or were interactive only with remote mousing or an android or iOS app.
The Brightlink 585Wi though, came loaded for big game, with full pen based interactivity, advanced networking, and a great picture.
But, enough said, other than lacking finger touch, the 585Wi is identical to the slightly more expensive Brightlink 595Wi, which takes top honors this year, as an ultra-short throw interactive projector. It's this simple. Want finger touch interactive, you'll choose the 595Wi, if your school district or university classroom doesn't need that, choose this 585Wi, and save a couple hundred dollars or so, per projector.
