I can just about remember life before mobile phones. There were good things and bad things about that time – we had quiet train journeys, but everything had to be pre-arranged as you couldn't contact people as easily. Mobile phones may have intruded on our privacy a little, but the benefits can't be denied.

The demand for mobile phones has increased at an alarming rate, so much so that manufacturers sometimes struggle to keep up with consumer demand. And when it seems that the market is saturated, companies bring out new models to tempt us to upgrade.

New features on mobile phones are being added all the time and our demand for hardware to run the new software and apps does not seem to be declining. Manufacturers such as Apple and Samsung mobile phones are constantly having to bring out new models to cope with customer requirements.

The new smart phones that are coming onto the market have increased memory for applications, photographs, videos and music. It is possible that in the future we will only need one electronic device to do everything, and that e-readers, mp3 players, and computers will become far less common.

With the development of technology and the new models of mobile phone, the price of the less complicated models will decrease, so it will be possible to get a really good bargain if you don't need all the advanced features of newer models. This way, there will be a phone to suit everyone's needs and budget.
