Rumours that Amazon is planning to launch a smartphone have been around almost as long as Alex Ferguson, but a report in the Wall Street Journal suggests the company might actually have two devices on the way.
The business bible claimed that Amazon is working on a pair of handsets, including one that will have a glasses-free 3D display.
According to the report, this high-end device will offer visuals that "seem to float above the screen like a hologram."
The WSJ also suggests that the mythical handset will also feature the retina-tracking technology that most observers expected to appear within the Samsung Galaxy S4 smartphone.
The smartphones are part of a host of projects underway at Amazon's hardware lab in Cupertino, California, according to the report.
The so-called "Alphabet Projects" are lettered A, B, C and D, the WSJ says.
Alongside the the two smartphones and dedicated audio streaming device, the fourth project may be the recently rumoured television set-top box.
It's possible that these prototype devices could never see a public launch, although we'd be very surprised if the company wasn't looking to compliment its Kindle Fire line up in some way shape or form with further mobile devices.
We would, however, be even more surprised if the Amazon smartphone eventually rocked up packing a 3D screen.
