It seems that everyone and their brother has at some point decided to enter their own pony in the smartphone horserace - Ubuntu, Firefox, Samsung/Tizen, etc. - and most have met with limited success. There have been a steady stream of reports that Amazon will debut its own line of smartphone soon, and the only thing I’ve heard that is somewhat unique is that they will include 3D support. If memory serves, LG made a 3D smartphone a couple of years ago, and it hasn’t been heard from since. What does Amazon have to do that is unique in order to succeed in a marketplace that has proven to be a challenge for companies such as BlackBerry, Microsoft, and others?
