I'm curious to find out what the 'best' algorithm is for deciding if you buy or not additional insurance. For example, when buying computers/displays, do you get premium insurance? What about rental cars? What about cars?
Generally you should only buy insurance if you would not be happy insuring yourself (e.g. buying a new one when it breaks). I fyou buy insurance then the profit margin and overheads of the insurance company are an extra cost over insuring yourself.
Buying insurance works best for expensive rare occurances (e.g. major car crashes) and not so well for cheaper, or more common problems (e.g. broken consumer electricals).
This is especially true with product insurance on products with a short shelf life (e.g. the latest iPhone) as their value drops quickly and better versions are introduced.
Just put the cost of insurance in a bank account for cheap common problems. Not only do you not have to pay the overhead, but the bank pays you interest. :) It should (but won't necessarily) average out.
