New Gadget and Technology, Do I Need It?

I have a dilemma about those things. Many people are following the trend on new gadgets and technologies. Some old friends of mine whom I knew from the past even already using the newest smart phones even I know that they probably don't use all the applications that they have on that phone. Most of them probably only use that gadget for sending sms, calling, and use their internet application to open certain social network sites such as facebook or twitter so they can chat or keep in contact easier with their friends and colleagues.

Now the question for me is : Do I Need To Change My Old Phone with that new gadget, smart phone which has high technology and application if the idea of changing it is only to keep in contact with few friends? I am not a busy business woman that has to spend my time outside the house or in the outdoor where there is no desk or notebook in front of me. Although I am pretty much busy at this moment, I still can have my notebook on my lap in some cases. So why do I need that new gadget?
