The world is experiencing massive changes in very short time periods. Product booms and busts are going from 10 years to 8 to 5 to 3 to 1 year. Computer hardware like PCs and Laptops are like throwaway cameras, use it for 1 max. 2 years and out into the trash can. PDAs (Palm Pilots), SLR cameras, pagers, fax machines, voice recorders, CD and DVD players have long since died. The list of dead or dying products is growing steadily.
Your phone is not just a phone, it is your digital office, your entertainment center, your access to the world. People put up what they had for lunch, where they had their party, or finished something mudane, or significant all through their Bluetooth, 4G enabled wireless phone - organiser - bank ATM - TV - social media platform. Everything is an app nowadays.
So, people like me are befuddled by the new media, and connectivity. Use it and be connected, but people can then trace your every desired activity, hobby, purchase, location where you had your holiday or dinner. Its Orwellian 1984, but without the unwiedly cameras following you at every turn.
Your phone is your best friend and your greatest enemy. Like fire, it can be controlled and used to good benefit, out of control and it will ruin your life.
