Alternatives to pizza delivery: Good or not?

There are certain appliances that seem ridiculous to have, like a countertop rotating pizza oven, but when you consider how long the savings will take to pay off the appliance, like two weeks worth of ordering delivered pizza, then it seems like a good investment, but is it really?

The convenience of the appliance may increase the frequency of its use, translating into an increase in the number of frozen food purchases that are used with the appliance, that in the end will cost more than just ordering delivery food. There is also the increased use of electricity to consider.

Then there is the cost in health. The convenience of the appliance will lead to an increase in the types of food that must be prepared by the appliance, typically frozen processed foods. If you had the original notion of the product's convenience in mind for its purchase, do you seriously believe that you plan to prepare healthy food with it? Besides fresh beef, fish, pork or poultry, if something needs to be cooked, is it really a good idea to eat it at all?
