My guess: the vast majority of the S60 devices are likely straight-up mobile phones, which may or may not have data features activated by the carriers. Ditto for windows mobile.
I think iPhone users are much more likely to have bought the device specifically for web browsing, whereas you're likely to see a lot of 'accidental' s60 or windows mobile users who just bought a phone, or just bought a phone with email capabilities.
Also, no one but Apple would actively promote the 2.5g service for web browsing (though having wifi helps). This is a marketing/user adoption issue.
I agree, however I'm still suspicious about the data.
I don't know how many iPhones have been sold, 10M? This would mean that iPhone uswers are 100 times more likely to surf the net than S60 users.
Could be, I am not sure what kind of marketing Nokia globally has for the S60 and browsing, and how aware people generally are of it.
It is easy to get a biased picture based on people around you. Me and a few of my friends surf train timetables/TV programs etc. almost daily on their S60 devices. And there aren't that many iPhones in Finland yet.
