I would say the smartphone has brought about enormous advantages to different aspects in our lives. Firstly, cell phones could be considered the most prominent means of communication. As far as I know, centuries ago people kept in touch via verbal conversations, and only by sending letters could they exchange information over a long distance. However, since the appearance of the cellular phone, those far conversations as well as abrupt contacts have no longer been a problem. What is more, the smartphone is also a cost-effective and portable shooting device. Over the past few years, smartphone cameras still hold great novelty value for capturing photographs. Also, this kind of portable device also comprises many other handy features, such as tracking maps, studying and researching, entertaining and so on. Thanks to the cellular phone, our daily activities are significantly simplified, which helps budgeting our time to complete tasks more efficiently.

Conclusion

To sum up, I would say that the smartphone has really made a great difference in the way we live. This invention might be so irreplaceable that I cannot imagine a day without my cellphone.
