Computer power will double every 18 months.
Every technology product will be better and cheaper in the future…just get over it.
Computers in the office will need to be replaced every three to four years. Computers over four years old can not be relied on to run the current software effectively. Plan to replace one third of the office computers every year and you will always be up to date.
One promise of ubiquitous “Cloud Computing” is that the heavy processing will be done by a computer in the sky not the computer on your desk. In that way we can use older, less expensive machines in our office and rely on the cloud server to be updated regularly to keep up with Moore.
But that is then, this is now.
