Poppa, it's called 'planned obsolescence'.

by making you replace frequently it 'forces' you to be up to date with modern technology.

your light bulb may be a good example; imagine if the older style lasted for years, then you would not be obligated to buy the new, environmentally friendly style. Where would the next generation (or two) be then?

the argument is that the running cost of the older style exceeds the replacement and running costs of the new type.

is it annoying? yes, but I think the 'logic' behind it is okay.

please note, none of what I posted is valid for motor cars; there is another factor to consider, the 'charm' factor, no one I know has ever looked at my light bulbs, and said "I like the look of the classics" etc
