This makes so much more sense. People are so lazy to type in their location that Google had to spend millions/billions of dollars on technology to stalk you and figure it out for you? I don't buy it.
I am doing that by downloading, parsing, rendering and evaluating the HTML and CSS. I'm not giving you arbitrary code execution. Do you want to fold proteins too?
I also think this is something Web people overlook. Our phones are _insanely_ powerful, yet almost all Web sites are slow-loading garbage: because of JavaScript.
