Hololens isn't VR...it's AR..
But rather than quibble over semantics I'm rather underwhelmed at all the hardware announcements. I agree that VR/AR both have great potential but am disheartened that nobody really seems to be talking about truly harnessing that potential. I roll my eyes at video watching (at least the 2D projected into 3D affair). Everyone's very quick to adapt current content into VR/AR, but very few are considering how to make something from the ground up tailored to it. At least in the near term. I would argue that these tailored experiences need to be available at launch for success. But I suppose that's a bit of a chicken and the egg thing. Content types don't want to invest in unproven (and low marketshare) kit and the kit needs content to drive marketshare.
That all said I'm really wondering if this so called partnership with Valve is much like the clumsy (non) launch of the Steamboxes. Piston? claimed they were Valve partners too. But in the end it seems valve likes to court hardware manufacturers with little care for real commitment. Unless Valve themselves announce this partnership I'm a little dubious.
