In 1924, representatives of the world's leading lightbulb manufacturers formed Phoebus, a cartel that fixed the average life of an incandescent bulb at 1,000 hours, ensuring that people would have to regularly buy bulbs and keep the manufacturers in business.
But hardware store LED bulbs have a typical duty-cycle of 25,000 hours -- meaning that the average American household will only have to buy new bulbs ever 42 years or so.
Iโve had my first-generation iPad for about four yearsโit was given to me by a friend who after buying it didnโt use it much. I use it nearly every day, chiefly for streaming Netflix videos and surfing the Web. It has held up fantastically: the battery life is still great, the screen is as bright and blemish-free as the day I got it, the displayโs touch capabilities havenโt diminished, and it still feels reasonably fast (though, according to Apple, the new iPad is 12 times as speedy).
