Luxury vs not a Luxury?

This very interesting article has quite a number of shocking revelations in it. I consider a microwave oven and a cable TV as a necessity and could care less about a cell phone. Take a look at the graphics in the article to see how your fellow citizens rate various day to day items as luxury or necessity. Do you agree or not? What appliance would you consider a luxury?
 
No longer do substantial majorities of the public say a microwave oven, a television set or even home air conditioning is a necessity. Instead, nearly half or more now see each of these items as a luxury. Similarly, the proportion that considers a dishwasher or a clothes dryer to be essential has dropped sharply since 2006.
 
These recession-era reevaluations are all the more striking because the public's luxury-versus-necessity perceptual boundaries had been moving in the other direction for the previous decade. For example, the share of adults who consider a microwave a necessity was just 32% in 1996. By 2006, it had shot up to 68%. Now it has retreated to 47%. Similarly, just 52% of the public in the latest poll say a television set is a necessity -- down 12 percentage points from 2006 and the smallest share to call a TV a necessity since this question was first asked more than 35 years ago.
