Roughly 100 years ago people began to hear of amazing devices that were being developed. Electricity for the home, radio and airplanes were a few of the inventions on the horizon. They were amazed at what was being produced and wondered at what modern science would invent next.
The technology that we have in our homes and so easily take for granted would have astounded them. Now we don't know what the next new thing will be because once again technology is moving fast.
Because it is changing so quickly what you had paid top dollar for a few years ago might now be considered outdated technology. It would be great to keep up but it would be foolish to buy the next newest toy every few months, you would be broke.
You need to take an inventory of the technology in your home.
