AN ESSAY - What are the advantages and disadvantages of mobile phones?
Mobile phones have changed people’s lives so dramatically and have become so common that discussing their advantages and disadvantages might seem to be superfluous (or useless). Most of us cannot imagine life without our smartphones (or "our lives without our smartphones"). Nevertheless, because of their significant influence, mobile phones should be used very carefully.
Everyone would agree that the most obvious advantage of using a mobile phone is the great possibility of connection. It is invaluably convenient (or "It is invaluable") that we are able to have a conversation with anyone whenever we want. Aside from just conversations, there is the bonus that we can give important information to anybody extremely quickly, just by tapping on a screen. ("Using messages" also works here but it doesn't really emphasise what you're trying to emphasise.
On the other hand, this is a bit of a double-edged sword (another idiomatic phrase): since I always have my mobile phone with me, the opportunity to call anyone at any time also means that I have to answer everyone. Obviously this can irritate me because it makes me interrupt whatever (or just "what") I'm doing at the time. However, I believe that we can reduce this inconvenience by using some simple rules.
^^^ What are these rules?
I got bored for the rest but I've corrected most of it. Now someone else should do the rest.
There is another aspect of this argument. I mean access to the Internet, which we always have due to our smartphones. But I believe that it is a completely different question.
To sum up, mobile phones can really make us less self-organised, but it is seem to me that humans will probably establish some helpful telephoning habits. In this case we will not suffer from disadvantages of mobile phones.
Good vocabulary however the fluency is a little bit lacking.
