HTML5 will take place web applications on mobile phones, says Opera

The Norwegian software developer Opera has high hopes the combination of mobile browsers and HTML 5 language that will allow web applications to better compete with native applications, according to the co-founder John von Tetzchner.

Currently, the combination of operating systems and diversity of native applications on smartphones is bad for both consumers and developers, von Tetzchner said in an interview. For consumers, it makes it more difficult to migrate to a new machine with different operating system, if one wants to keep their applications, developers have almost always have to start from scratch when they create applications for different platforms.

Use the web becomes an antidote to these two issues and, like Google, Opera is betting that HTML5 will make web-based applications more competitive compared to native applications. The browser was not designed for building applications, but the arrival of HTML5 changes this scenario, according to von Tetzchner.
