90% of websites still not optimized for mobile. Will HTML5 change this?

Less than 10% of websites hosted today on professional hosting platforms are optimized for mobile devices said Mozilla CEO Gary Kovacs at CTIA.  He also admitted that web browser manufacturers had been slow in adapting their technology to Smartphones.
However, he said a bigger issue and pivot point for the industry was the emergence of HTML5, which will usurp the walled gardens erected by Apple, and represent a stranglehold over mobile apps that compete with the browser in terms of user engagement.
64% of the time people spend on their Smartphones, is spent inside an app.   However, Kovacs believes this is all about to change with the promise of the new HTML5 standard, which dictates how websites should be coded across browsers and devices connected to the Internet.
A CNET report said that by 2016 more than 2 billion devices will have HTML 5 browsers. And he said that many sites are already being built to be HTML 5-ready. Kovacs expects the momentum to continue in spite of some technical challenges.
There is a thus a pitched battle underway between developers who build mobile apps and those developers who build sites with HTML5 which will allow applications (including video) to play natively in the browser.
Kovacs believes that developers worldwide are getting restless with the mobile app restrictions residing under an .e.g. Apple walled garden.  He points to the growing surge of new mobile apps on Android platforms, which are actually designed to improve the browsing experience.
“He warned the industry must adopt standards for mobile browsers to ensure that wireless subscribers can easily access web pages, games, video, and other content outside of apps without being stifled by proprietary roadblocks,” said CNET.
The Internet was built on the idea of freedom and technological openness. This philosophy needs to be extended into mobile device development to avoid future bottlenecks for web users.
“”Are we going to make history or repeat history?” he asked. “If we learn from the past, this can be a collective leap forward. And we will usher in an explosion that all of us can participate in.”
The new HTML5 standard has already forced Adobe to drop the flash player and re-engineer the animation technology to support HTML5.
“Our future work with Flash on mobile devices will be focused on enabling Flash developers to package native apps with Adobe AIR for all the major app stores,” said Adobe.
“ We will no longer continue to develop Flash Player in the browser to work with new mobile device configurations (chipset, browser, OS version, etc.) following the upcoming release of Flash Player 11.1 for Android and BlackBerry PlayBook.  We will of course continue to provide critical bug fixes and security updates for existing device configurations.  We will also allow our source code licensees to continue working on and release their own implementations.”
