If your old phone does what you need it to do, common sense says you don't need anything else and this is the sustainable position. If, on the other hand, you have been convinced by the marketing mind control manipulators that your phone needs to hold and work your entire life, the i-phone does it very well. All you have to give up is enough money every month to pay for a Porsche. It is truely amazing what an i-phone can do. Hell, I can set my living room vcr from 1,000 miles away but, do I really need to? Would the world end if I couldn't record honey boo boo? Probably not but my life might be less complicated. It' a question I am pondering.
