A friend here at IIT is a great inspiration for me -- he always buys the cheapest product available. He owns a Nokia 1100, while I paid a grand or so more for a phone with a higher-resolution color display and a better shape. Sure these things are nice to have, but not really needed. A phone is for making and receiving calls, and anything beyond that is unnecessary. We live in a culture where you must have the latest and the greatest, rather than what you need. Most people, I guess, have a weak willpower, and we become slaves of the marketing assholes.
Next time I buy something, I'll ask myself if I really need it or if a cheaper product will do the job
