"Searching the Web via a mobile device presents an enormous opportunity for both search engines and consumers," said Jon von Tetzchner, CEO of Opera.

"Almost all search engines are moving forward to offer relevant and timely information based on location. Yet, consumers prefer services from the search engines they already know and use. As the mobile Web becomes more pervasive and more people have their first experience on the Web from a mobile device, it will be fascinating to see how these habits might change. We are certainly only at the beginning of the mobile Web revolution."
