Now that Android 7.0 Nougat is beginning to ship on phones, and the holidays are around the corner, Google is releasing accessories to support it. The Daydream View, which you can dock phones into for VR purposes, will be on sale on November 10th. The viewer will cost $79 USD, minus the phone of course, and can be purchased in the US, Canada, UK, Germany, and Australia.
Currently, the only Daydream-compatible phone is Google's Pixel. As mentioned before, Nougat is only beginning to ship on phones, and the OS is required for this feature. One thing that's not entirely clear to me, after reading several sites, is whether all Daydream-compatible phones will be able to use this specific viewer, or if some will need a different chassis. You would think that variations in attributes like screen size might complicate things, but we know it will support other, non-Pixel phones; I'm just not clear whether it's some or all.
Anyway, that concern aside, it's almost cheap enough to be a “why not?” addition to any phone that is compatible. It certainly will not put the HTC Vive PC-based VR system out of business, but I'm interested in how it works with mobile content, especially linear video, going forward.
