Wi-Fi More Prevalent Than Ever Before

A recent study claims that more than six in ten households with Internet access also have a Wi-Fi network. With the prevalence of Wi-Fi at an all time high, it's easier than ever before to surf the web from your PDA. Many new PDAs and PDA-like devices (including the iPod touch and iPad) have built-in Wi-Fi capabilities, letting you check email or social networking sites from the comfort of the couch.
