This surely does mean, that people still like to use it as part of their everyday communication between friends and loved ones. There is really more than one reason why we love to use SMS for communication.
Cheaper than calling
Sending SMS text messages is much cheaper than actually making a call from one cell phone to another.
Easy to use
Everyone, old or young knows how to use use it. SMS has been one of the oldest feature on mobile phones.
Straight to the point
People tend to text only the important part of their message whatever it is a question, news, greetings etc.
So in this light, I'm pretty sure that even with everyday technical progress messaging has long future ahead in our lives.
Keep texting! :)
