Cell phone and wireless laptop internet use have each grown more prevalent over the last year. Nearly half of all adults (47%) go online with a laptop using a Wi-Fi connection or mobile broadband card (up from the 39% who did so as of April 2009) while 40% of adults use the internet, email or instant messaging on a mobile phone (up from the 32% of Americans who did this in 2009). This means that 59% of adults now access the internet wirelessly using a laptop or cell phone—that is, they answered “yes” to at least one of these wireless access pathways. That adds up to an increase from the 51% who used a laptop or cell phone wirelessly in April 2009.
