Re: It's called competition
Actually Mark the evidence is against your assertion. Volume of sales does not equate to a vote for which is better and I don't even need to provide examples of an assertion so obvious as that. Not that reason will make any difference to the response this gets :)
Two metrics that do provide a fair basis of comparison are satisfaction ratings and resale value. iPhones come our in front of any Android phones on both counts for sure - though for the first time for iPhone, since the Maps debacle, satisfaction ratings have fallen. However they still remain higher than for e.g. the S3 by some margin. This new Nexus may of course change that, but it is fair enough to point this out because your statement is referring to Android devices to date.
Additionally there seems to be evidence Android phones - outside of a tech clique (which are only a tiny proportion of sales beyond first day) - are not purchased by people who are really that into using smartphones. Data usage by iPhones is still proportionately much higher per user than is the case for Android (despite some initial reports in 2010 to the contrary) and pundits for some time have had difficulty understanding why that should be, but one interpretation is difficult to avoid; Android phones, perceived as the cheaper alternative by the general market, are purchased by a higher proportion of people who don't want to be left behind but who aren't particularly into smartphones or don't wish to allocate budget to purchasing an iPhone. Consequently they are used for core phone functions and maybe for camera and music, more than for web browsing and a wide range of apps (which is also backed up by the still far lower revenues and profit margins for apps developers on Android).
None of this changes how an individual might feel about an operating system, so it is is still perfectly consistent to say for those who are really "in the know" Android is better. However let's get some perspective as this forum is descending into a circle every bit as jerky as any formed by Apple fanboys.
