These statements contradict each other. Amazon isn’t utilising the software itself but is actively encouraging a “new breed” of applications? TechCrunch seems to be implying that Amazon will downplay a feature that they have dedicated a lot of hardware resources towards making possible.
I don’t think Amazon is stupid. They must know that if you go to the effort of fitting something with special sensors, it is wasteful not to (tastefully) exploit it everywhere possible. In contrast, BGR’s report (which includes pictures of a prototype unit) claims Amazon is aggressively applying the 3D feature across the system.
