Opera is focused on disseminating its products for the "one Web," as opposed to devoting more energy to the development of either mobile or desktop browsers, according to Opera co-founder Jon von Tetzschner, who suggests that Web browsing will become a common feature of not only smartphones and PCs but other devices such as televisions. Nonetheless, Opera has lately been focused on disseminating its mobile browser franchise, with plans to release Opera Mini for the iPhone as an App Store application, following the release of the beta version of Opera Mini 5 for Google Android and Windows Mobile 5.x and 6.x. Common features across all versions of Opera’s mobile browser include tabbed browsing, a focus on increased speed, and 90-percent data compression. Von Tetzschner claims that Opera’s desktop-based and mobile browsers have between 120 and 150 million active users worldwide.
