Stupid or simplistic... or both.
Talk about muddled thinking!! If you were to forge a policy on this survey, you would be almost 100% wrong. The survey actually begs the question, why is the majority of phone web access done by one phone?
I think you could only draw the conclusion that 'The majority of internet able phones do not access the web on a regular basis' from this survey - and that's all.
I think even a novice looking at the stats would rapidly see that the only regular web using phones are the new smart phones - not that Brits are left cold by mobile access. In fact, if you were to sample each and every iPhone user you would get a 100% web return and probably much the same for Android and Palm users which goes to show that if you make it easy to do something, people will do it. The opposite conclusion in fact.
If I remember rightly, Steve Jobs said when introducing the iPhone, that accessing the web with existing phones "sucked" because it was slow, awkward and unreliable, so it wasn't happening. With the iPhone they made it a simple one touch option and guess what... everyone uses the feature and loves it. With this in mind, it's simple to rank the phones in order of how easy it is to get the 'full' web - which most of the phones out there can't do anyway.
Now if they had asked each of the sample respondents which phone they were using, they would have exposed the poor web implementation of the majority of phones out there but that would be far too embarrassing for those manufacturers and given Apple a seal of approval. And how do you sell a report that simply states that Apple, plus a few others, are doing it right and the others are hopelessly wrong.
As always, the usefulness of a survey and the resultant stats, is totally dependent on asking the right questions.
