Fortune Senior Editor and Author Adam Lashinsky speaks with Edie Lush at Hub Davos about his new book, 'Inside Apple'. Apple controls everything - from the specific messages that are allowed out - i.e. 'revolutionary phone, the internet in your pocket, the best ipod ever made' to the few executives are ever allowed to spread the message. They are told not to deviate from the script, at all, ever. They famously don't do market research, or focus groups, but rather Steve Jobs decided what we wanted, and gave it to us. The new CEO Tim Cook is not Steve Jobs, and comes from the manufacturing side, and it remains to be seen what kind of control he'll have over the company.

Angel Investor Esther Dyson talks with Executive Editor Edie Lush about the differences between the political protests - from the Occupy protestors in the US (and Davos!) to those asking for change in Russia and the Middle East. In the US there is a coalition between Democrats & Republicans who are against both big business & big government. In large part these are people who have lost their jobs or are working in low paid jobs. In the Middle East, there is a huge amount of young people who can't get jobs and are clamouring for change, where as in Russia it is a middle class movement. Social media is playing a critical role in the movements. Social media means that the Russian government can't rewrite history as they have before, because the people are writing their own history through Facebook and Twitter posts. Mobile and internet penetration means that the Russian movement is also much wider than the Middle East, where internet penetration is shallower.
