Then it's not a working prototype. Since they claim they'll have their own UI layer on top of Sailfish on the phone.

3 weeks ago they said production had started and first customers would receive their device in the first week of June. They then deleted that comment. Comment now says on FB (from a couple of weeks ago) that people will receive their phone in late June (oh yeah?). Their Twitter has still been dead for 7 months, and website's still dead.

Regarding it being 'advanced' ... it has an SD801 in mid 2016, assuming it actually launches. The lower mid range Mediatek chipset in the Oyster is much faster. The specified screen is something that plenty of $250 Chinese phones can easily exceed in quality. I'm assuming the camera, like the main chipset is an end of bin, years old, bargain Sony unit, which was high end once upon a time, but would shame most cheap devices these days. The unobtainium alloy is what people are supposed to stump up $800-1K for? Really?

Gestures and Android:

There's no reason not to use almost entirely gestures now, as @mscion hinted at, if you're happy to root your phone (usually a simple process). The gesture options are also far more comprehensive and configurable in Android than we've ever had access to in 3 years of 'development' of Sailfish, as a supposedly gesture based OS.

Still, hardware buttons do have some use. If you have sweaty, wet or sticky hands, soft keys and gestures aren't much fun. Same regarding gloves in winter.
