Cordless phones are a highly useful purchase to have around the home, which greatly increases the range of uses that you can get from your normal phone. This makes it far more enjoyable to keep up with your correspondence as well as making you far more productive.
We all have people that we need to call regularly, and many of us know at least one or two people who will natter on for hours on the phone if given the chance. These people might be grandparents, parents, old friends or even long distance partners. While speaking to these people might be highly enjoyable, and it probably is something you want to do if you've maintained this relationship, it is still something that takes time, which we are increasingly pushed for in a modern world. For instance we might have just come home from a long day's work, or we might have arranged to call someone only to find that we have to go out in an hour to deal with some kind of emergency. All of us it seems are these days putting out fires all over the place.
Cordless phones can make all of these things far more practical and enjoyable. Take for example the first option. If you come home from a long day's work and have to make a phone call then normally this is something that has to be done sitting on a chair perched by the phone. This is far from comfortable, and not the relaxation we likely had in mind when we were in the office. However with cordless phones we can sit anywhere while talking to friends - on the couch, on our bed… even outside in the sun. Rather than being something we have to do before we can relax then, cordless phones make phone conversations something that we can do to relax.
Similarly we might use cordless phones as a way to increase our productivity and fit more into our day. In the previous example of having to make a call before going out for example, this can give us the opportunity to get our things together - having a bath, getting read, packing a case or bag… all of which while talking on the phone. When you don't have to go out, cordless phones mean you can chat to your friends while washing up or while ironing. This not only means you get more done (and then can relax completely later rather than taking literally twice as long on those tasks and having no time to yourself) but also means that you can enjoy the washing more as time will pass faster as a result of getting to chat to your friend while it happens. This becomes even more useful when it is not a leisure call we have to make, but one to a bank or to our electricity supplier, where we may have to hold for a long time while waiting for someone to answer and can this way just put the phone on speaker and carry it around with us until they answer.
