Editor's Notes
- #6: IP addresses in the first 3 categories.
- #8: In other words, what we take for granted today had only been conceived in the world 5 years ago. Compare that to other technology areas – PCs and their OS, wireless technologies, GPS technology and devices, voice and handwriting recognition, flying!
- #14: Becoming a duopoly! If I were Blackberry I’d be very worried. If I were Microsoft I’d be smelling a great opportunity.
- #16: Examples of Hybrid frameworks: Titanium, Icenium with Apache Cordova,
- #24: - On a PC when a user searches they’re looking for answers to a specific question. However on a mobile device a user is looking for a direct and personal experience when it comes to information access/query.
