A want is something to satisfy you for your pleasure whereas a need is somewhat of a requirement that is necessary for one’s life (food, water, shelter, etc.).  I believe you don’t need to have the latest technology, especially if your product/model is functioning perfectly fine.  However technology in general is very important since society today heavily depends on it and many benefits come from technology.

I agree, such as todays circumstances, we need technology in order to communicate as well as learn. But about a year ago, we might have been saying otherwise.
