In the article “Chip Makers Watch Sales Fall Sharply” by Ashlee Vance posted at http://www.nytimes.com/2009/03/03/technology/03chip.html?_r=1&ref=technology in the New York Times. She states that some companies that make the chips for electronic devices such as cell phone, iPod etc. their sales are declining drastically due to the fact the recession is affecting their product sales. For example,” Consumers have benefited from some of the underlying turmoil”. She explains that Computer companies needed to sale their products to the consumers and in order to do that they needed to lower the prices as a way to attract customers and increase their profits. Even though, they are trying to increase their sales it won’t be as previous years. Therefore, I would recommend to anyone that needs to purchase any electronic devices to do it now because the good deals don’t last forever.
