iPhone users spend less time talking %wise - not surprising, as they have the option of webbing/mp3ing. You may find it hard to believe, but a lot of people have phones which don't play mp3s or web browse - they spend 100% of their "phone time" talking/texting. Any phone which can do more things will do (proportionally) less talking/texting. What we need are absolute figures, not percentages.

And, no, I don't have an iPhone!
