I wonder how relevant is the question asked in the original article, or - maybe better said - to whom the question has been asked. >The researchers asked real people of various socioeconomic strata if they were willing to travel an extra 30 minutes to save $50 on a $300 tablet. Some said they were. But when asked if they’d drive that far to save the same amount on a $1,000 tablet, some of the respondents changed their minds. Their answer depended on their income. I wouldn't even think to ask such a question about buying a $300 (let alone $ 1,000) tablet to someone who clearly cannot afford it (the actual poor people). I mean, when you are dealing with someone who is homeless or that is on foodstamps (or similar assistance for the very basic needs) are you really going to ask them about the $50 savings on a completely voluptuary item such as a tablet, particularly a $ 1,000 one? And the question is about "driving" (implying that the "poor" has a car).
