Some 34 percent of Internet users surveyed said they have logged on to the Web using a laptop computer, handheld personal digital assistant or cell phone.

Four in ten (39%) internet users have laptop computers and of these
laptop users, 80% say their laptops can connect to the internet on a wireless network.
Most of the time, those with wireless enabled laptops connect to a wireless network at
home, although most also have logged on from someplace other than work or home.

Among laptop users whose machines are capable of connecting to the
internet wirelessly:

• 88% of laptop users have at one time logged on using a home wireless network.
  
• 57% have used a wireless network someplace other than home or work to connect to
  the internet.
  
• 36% have logged using a wireless network at work.
  

“The growth in wireless networks at home has undoubtedly fuelled the use of laptops to
connect wirelessly around the house. One in five (19%) of internet users have wireless
networks at home, which is twice the number recorded when the Pew Internet Project
asked this question in January 2005, when 10% of internet users had home wireless
networks”.

The survey of 798 Internet users has a margin of error of plus or minus 3.8 percentage points. Detailed results were posted on the Web at the Pew site.
