Seems really cool. Great for people who want a big-screen cinema experience that is also compact, portable and on a small budget.

On the business (office presentations) and education side, I imagine it can being very convenient too. You don't need a dedicated room with a projector anymore, but you can just use this pico-projector that people can carry around. The price and resolution is also fantastic for the kind of product that it is. (other pico-projectors are typically only 480p resolution and are in the €250-400 price range. 1920x720 resolution is a first for a pico-projector as far as I know, so great engineering achievement on Sony's part)

And by the way, you can't really compare the luminous flux in lumen from a laser projector (which this one is) to a bulb-based projector (DLP). Laser is always way lower because light is focused in one direction. 32 lumen for a laser projector is decent and considering the small form factor of this projector, it's pretty good I'd say.

The technology will probably be very important going forward too, with the emergence of AR glasses/HMD's that utilize small built-in pico-projectors. So good they're doing R&D in that area I think. Integrating it in smartphones is definitely also a possibility, like the article mentions.

And by the way, it isn't a PS4-specific projector. It was just demoed with a PS4 going by another article that I read, but it can obviously accept any HMDI video source. (and even receive stream from other devices, so pretty versatile I'd say) Using for playing games with a PS4 is one of the many applications.

The article is needlessly opinionated though. I don't see how it's pointless at all.

No offense, but article is needlessly opinionated (video games for consumers is just one of the many potential applications of this projector). It is not a useless product at all. Just because it isn't useful to you, doesn't mean that it isn't useful for people in other fields.

I think it can never hurt to do a bit more research when you're writing something that isn't that much about gaming but is more related to technology.
