Insuring laptops and other electronic equipment such as Global Positioning Systems (GPS), portable MP3 players, cell phones is as simple as adding these items to the "specified" section of your short-term household contents insurance policy. It is important to note that some insurance companies will not cover the loss of laptops or other expensive, portable electronic devices unless they are specified. This is due to the fact that these items are a favourite amongst criminals as they are highly portable, valuable and extremely easy to sell. For businesses, the value of laptops, in particular, is often two-fold. Not only is the portable computer on its own of financial value, the data contained on the laptop may in fact be worth considerably more than the actual computer itself. For that reason, many companies are moving towards encrypting hard drives which contain valuable information.
