     Cell phone feels like a part of your body? A global survey has found that most people can't live

without their mobiles, never leave home without them and, if given a choice, would rather lose their wallet.

     Calling mobile phones the "remote control" for life, market research firm Synovate's poll (民调) said

cell phones are so ubiquitous that by last year more humans owned one than did not.

     Three-quarters of the more than 8,000 respondents (受访者) polled online in 11 countries said they

take their phone with them everywhere, with Russians and Singaporeans the most attached. More than a

third also said they couldn't live without their phone, topped by Taiwanese and again Singaporeans, while

one in four would find it harder to replace the mobile than their purse. Some two-thirds of respondents go

to bed with their phones nearby and can't switch them off, even though they want to, because they're

afraid they'll miss something.

     "Mobiles give us safety, security and instant access to information. They are the number one tool of

communication for us, sometimes even surpassing face-to-face communication. They are our connections

to our lives," Jenny Chang, Synovate's managing director in Taiwan, said in a statement.

     Mobiles have also changed the nature of relationships, with the survey finding nearly half of all

respondents use text messages to flirt, a fifth set up first-dates via (通过) text and almost the same

number use the same method to end a love affair.

     Apart from the obvious calling and texting, the top three features people use regularly on their mobile

phones globally are the alarm clock, the camera and the games.

      As for email and Internet access, 17 percent of respondents said they checked their inboxes or surfed

the Web on their phones, led by those in the United States and Britain. One in 10 respondents log onto

social networking websites such as Facebook and MySpace regularly via mobile, again led by Britain and

the United States.

     "As the mobile becomes more and more an all-in-one device, many other businesses are facing

challenging times. The opportunities for mobile manufacturers and networks however are enormous,"

said Synovate's global head of media, Steve Garton.

     Not everyone is tech savvy (科技通), however: 37 percent of respondents said they don't know how

to use all the functions on their phone.
