Having the latest technology is a want.  I have gotten one new cell phone in my lifetime because the phone that I have now is fine, so anything more would be a want.  The environmental impacts of these technologies can be bigger than you think.  One of the problems have been e-waste which is essentially electronic waste.  The throwing away of these technologies is actually polluting our environment!  Another problem is that these technologies when left on and over used actually use a lot of energy.  Turning cell phones off are ways to conserve some of our energy use.  If you are addicted to buying the newest technology all of the time. maybe consider what you have first and stick with that unless you really need something new.
