Below, we sum up the current status quo of this debate by listing 10 advantages and 10 disadvantages of mobile phones.
Top 10 Advantages of Mobile Phones
1. They are convenient.
It’s great being able to call a friend when you are out and about – without being tied to a land line.
2. They can be life savers.
Taking a mobile phone with you when you go hiking is a basic safety precaution. If you lose your way or get stuck in bad weather, your mobile phone could just save your life.
3. Staying connected.
There is no need to feel lonely when you have a mobile phone in your pocket: just connect with friends via text, FaceTime, voice calls or social media.
4. Fun and games
These days, mobile phones are loaded with all kinds of fun games. We all remember Nokia Snake, but more recently people have got way more into challenging their brains with Sudoko or whiling away the time during a long commute with a game of Candy Crush Saga.
5. Your mobile keeps you informed.
Whether you are searching for that Spanish word you read in the newspaper or reading some articles on a topic close to your heart, mobiles that are connected to the internet are a treasure trove of information.
6. Getting snap happy
Sophisticated cameras mean that you can take professional quality photos on your humble cell phone.
7. Knowing where you are
GPS technology enables you to pinpoint yourself on a map no matter how lost you are. Just fire up your phone to see your position and create a route to your destination.
8. A handy torch
Turn on the flashlight function on your mobile to find your keys in your purse as you step off the bus, or to locate the candles when there’s a blackout in your house.
9. A recording device
Record the dawn chorus or your friends singing you happy birthday – all on your mobile phone.
