Technology has come a long ways in the past 30 years. And it was less than 20 years ago when the idea of a small mobile phone came to the market. Before that model, people carrier around a large unit that had the normal phone handset on the top looking about the size of a small suitcase. These were not light either. It has been many years since then and mobile phones have continued to get lighter and faster over the last 10 years. Few are sold today that are not thin in size. It would be fun to see someone holding up one of those old home phone handsets to their ear to talk with someone using their new smartphone.
And you can have one of those Retro handsets attached to your new smart phone. That would cause people to stop and stare wondering if they were actually seeing what they are seeing. You can pick up one of these through Amazon and there are even a variety of colors available. The concept is simple and they plug into the standard 3.5 mm jack you see on new smartphones. The Retro smart phone handset plugs into that and is ready to be used at that point.
Reportedly, they have noise reducing technology associated with this and the say this will reduce up to 99% of the radiation you would get holding the phone up to your ear. If you want to have some fun, take a look at this one.
