I guess that's not the question I need answered as much as something more like "If I used feature X or require limit Y, what percent of the world market will be excluding". Given the list of sites, I don't think the data will show me the long tall of low powered older phones that are used by the majority of people because the people visiting sites like those on the list are more than likely to be tech people who have newer tech. PS, I'm not dissing the site or your effort. It's awesome that you put it together. Rather, I'm saying the numbers are not reliable. You can't say "50% of people can use feature x". You can only say "50% of people that visit sites like those listed can use feature x". I suspect that 50% is way way off. It's more like only 10% of the general population can use feature x" Here's hoping you can get one or more mainstream sites to add your survey script.
