While we're starting to get some crazy mixed reality tech using projectors, it's good to see companies haven't forgotten about good old-fashioned home cinema. Over the past year, manufacturers have been lining up to show off their little light emitters that pack big features. In June, Optoma unveiled its 4K projector, which at $2,000 is considerably cheaper than its rivals. Even Chinese behemoth Xiaomi is muscling in on the turf, promising a laser projector that uses the same system as movie theatres for less than $1,500. Not to be left behind, industry heavyweight Epson just unveiled its own thoroughbred. The company is touting the new Home Cinema LS100 as an "ultra short-throw" laser display. What that essentially means is you can park it just inches away from a wall, and it will still light it up with a 120-inch, full HD picture.
