The end of email has been foretold many times, but despite these predictions of doom, U.S. workers can't seem to get rid of it.
About six in 10 Internet-using workers in the U.S. list email as "very important" to doing their jobs, topping the list of most important work tools, according to a survey by the Pew Research Center.
Email trumped the Internet as a whole, which 54 percent called very important, and ranked well above mobile or smartphones [24 percent] as well as social networking sites like Twitter, Facebook and LinkedIn, which only 4 percent of workers found important. Surprisingly, the use of landline phones outranked mobile phone usage: 35 percent of respondents marked landlines as very important.
