• Movement of power and money (from carriers to OS and app developers)

• Standardisation of UIs, equipment, apps, add-ons and infrastructure

• Appification of the Web

• Focus on the inside of devices, rather than the outside (1990-2007)

• Usability improves. Now not only geeks that used phones and tablets

CHALLENGES

• High cost of devices and access?

• Radiation?

• Less social – not more?

• Important focus away from the open web and into closed apps

• Too much compromise when replacing special hardware with mobile app solution

• First wireless phonecall, 1880

• Big jump 100 years ahead to the GSM standard (Groupe Spécial Mobile)•Expanded to include data capability (GPRS and EDGE)

•Later improved to form the 3G (UMTS) standard (0.2-9Mbps)

•Will evolve into 4G (likely LTE) standard (potential Gbps)
