I think only one solution for sony to fight against amazon
Make an official android update
I mean a light is useful, but for years people read books with a lamp, putting android(pity for the audio) and releasing a super firmware busy on remove bugs and implement new functionality is the best thing to do. Please crunch the numbers and enquire about the doability!
Actually I think I could work as bus analyst in this field.
if you want to offer me a well paid job and a fixed contract in adam you are welcome.
