In my opinion, something new always wants to be followed and owned by some people, because it can be considered not following the development of the times. For those who do have more funds, it is not something to be afraid of, and they are sure to be able to buy. But there are some people who onlyn't they want to be appreciated or recognized for their existence in development and try to be able to buy even though they don't have the ability to buy it, in the end they do everything and not a few who confiscate their savings.
Even though what is needed is the usefulness of the device, not the trend that is more recent, and even then, it is certain that it is usually not much different from the old one, only a few changes.
It is not bad to get something new and that is better than others, but the most important thing is that we need to think when making plans to get this stuf if it is something that can be afford without one be affected financially. It is a financial mistake for people to strive on what they can't afford comfortably. When one is not financially buoyant to get something that can't bring value, I think it is a waste of money spending huge amount of money just to follow the trend and to feel among of people using the latest.
If that makes you happy then do it as long as you didn't take any loan just to get the latest smart phone in the market. Sometimes we need to satisfy our self since buying those stuff will somehow make us happy. Although we understand that latest phones cost a lot of money but if you are capable to acquire it since you have lots of extra funds to spend and as said that it will not affect your financial state then do it.
Although I understand that its waste of money to buy those gadgets just to get updated on the latest but if that's your happiness and again have lots of money then people will not question you on why you acquire it. But for certain individual struggling in life I guess much better for them to spend their money wisely and just buy new phone when their current phone is not working anymore.
