We do not believe in the killer app. Multiple apps is what we think will drive mobile broadband. But if there be a killer, it will probably be search, as this NYT article suggests: Today, Google says mobile searches are growing as quickly as Web searches were at the same stage in the company’s early days, and they are up sixfold in the last two years. Google has a market share of 97 percent for mobile searches, according to StatCounter, which tracks Web use. Now that it dominates the field, Google is throwing its burly computing power and heaps of data at new problems specific to mobile phones — like translating phone calls on the fly and recognizing photos of things like plants and items of clothing But it search reinvented, not the same old, same old.
