Peter's MVIS Blog: Surface Phone -- Maybe this is related.

I always knew something was bugging me about the Surface Phone -- some dot that needed to be connected that wasn't connected. I found it.

Microsoft has talked about the "Surface" line of products, and then about the "surface phone." They're confident about the surface phone that it's going to be a game-changer.

I know this article doesn't mention Microsoft.

This may be why.

Recently, a post here about the Surface phone going into trial production. From November 29, 2016.

The Surface phone is also mentioned along with something called Microsoft Continuum -- which turns your phone into a "big screen projector."

"We can’t say for sure when the Surface Phone is going to come out, but we know that it’s on the way. In November, Microsoft CEO Satya Nadella told the Australia Financial Review that Microsoft is working on the “ultimate mobile device”, admitting that the company “missed the mobile boom”. That’s not confirmation of the "Surface Phone" name, but it’s clear-cut proof that a new mobile device is on the way."

So, it could come out at any time now (spring 2017?) Who knows what it's going to be? We don't know.

Back in what is essentially the archives there's something really, really cool.

The first time this PDF was found was in early 2014 (February)

And, yes, it does use a Microvision PicoP projector -- it is labeled in the drawings.
