The latest rumours suggest Amazon has 2 phones in the pipeline. A budget and a top flight offering. Both will offer easy access to all of Amazon’s services and products. The top flight phone is rumoured to use a 3D interface. Lets hope motion sickness is not an issue with this sort of display.
The key aspect of these devices is the pricing. Will amazon offer these at cost and once again disrupt the smartphone market as it has with the Kindle Fire tablets.
I still perceive Amazon as the biggest threat to all smartphone/tablet manufacturers. It already has the eco system and the largest most diverse shopping offering.
