The article says that the USA as a whole has a lower use of secured AP. So unless there are huge numbers of unsecured APs in the rural areas of America, the large cities (with their secured APs according to this theory) will swamp the results, yet that doesn't seem to have happened. Therefore I think population density isn't the major factor, and this is bore out by the fact that Sweden and Norway (countries with low density) can come higher than higher density countries.

The densities for the larger European countries are ordered: Netherlands, Belgium, UK, Germany. While those countries were high on the list, it cannot be all there is too it as Spain comes top.

I have to say I'm disappointed by this. I much prefer the simple interface of the spatial view.

Where was that file I was looking at earlier? Open folder, there is is exactly where it was the last time I was in this folder.

Oh well another simple interface lost to the bells and whistles brigade.

How people say it doesn't figure into the equation.

It sure as hell does when we're talking about speech recognition, or have you forgotten that part of the discussion?
