<i>"consumers spent an average of 81 minutes per day using apps on smart phones and tablets, versus 74 minutes surfing the Web through a PC or mobile phone browser"</i><p>But how much time do people spend using apps on a PC? You might draw different conclusions that the article if I told you that these same consumers spend an average of 186 minutes a day using apps like Word, Excel, Outlook, and so on (a made up stat, btw)<p>And to include time spent on the Evernote iPhone app (say), but exclude time spent on the Evernote PC app is disengenuous at best.<p>People spend so much time using mobile apps because pretty much every task just takes longer on a mobile app than it does on a PC. Typing, for example.<p>And finally: how much of this smart phone app usage was games? That people prefer casual gaming on an iPhone to casual gaming on a flash browser is not new or particularly surprising, and doesn't support the central thesis of the article.
