Coca Cola had this catchy ad campaign many years ago that said if you drank a Coke, it was
THE PAUSE THAT REFRESHES
I am convinced from myself and watching others we need to FORCE ourselves to do this refreshment trick with technology every two or three years. My hard disk finally crashed on a laptop and I got a new one with the new Vista operating system. A friend's cell phone was going on four years old, falling apart, battery not lasting long, and he finally is going to get another one. A woman title company officer I know complained her first generation Blackberry PDA didn't have some kind of back space function and everyone in her office said she had the oldest model.
Getting new "updated" technology from time to time just feels good. You get refreshed. Quit being cheap and stodgy. Spend some bucks and REFRESH!!!
