2. If I had more time, I would speak slower The great French writer, Proust said “If I had more time, I would have written a shorter letter”. Here are my shorter slides:-)

3. 4 Areas We don’t want to pay for bits anymore I.e. cellular provider better make money from something else We do want to know who to trust Source of identity and risk reduction Especially for transactional software We woul like to go back 10 years to 1 week battery life handsets! Need to be smarter about resource use on mobile We’d like to automate malware out of existence Not just signing and virus scanning - better Computer Science!

4. Lessons from working with cellular providers They have lost control of the handset They will lose control of the radio/spectrum pretty soon Need to capitalise on last resources - e.g. Cell tower is good co-lo for cache/web/CDN SIM is great for ID Low transactional overhead billing system is excellent

5. From experience with Microsoft, Intel, NTT DoCoMo, BT, Telefonica, KAIST, MPI, Vodafone Etc etc etc Trust matters Ethics matter Spectrum should all be free Models based on empirical data matter measure everything about your users, networks, devices Social Structures are really really useful Old ideas (e.g. dataflow and functional programming) may have their day
