Facebook CEO Mark Zuckerberg went on record yesterday discussing their recent move to a native app in Apple’s iOS. The facebook app had been developed in HTML5. Now I am not quite sure why a company with the resources that facebook does would have even considered an HTML5 app vs a native as native is definitely better, however, they did. But why was it a mistake? Because Apple has chosen to not allow HTML5 apps to run as fast and smooth as native ones.
So what is the future of HTML5? Well at this point APPLE does not want to support HTML5 mobile apps. Why? They lose control and money. Sure they are supporting it in the browsers but they are not supporting it in apps. Why would HTML5 apps be good for developers? Because you could develop one app and publish it to all mobile devices. So for instance, Apple has purposely made apps running HTML5 run slower than they would as webpages in their browser, citing security and stability concerns. While it might be valid it a very suspicious as Apple has been trying to tell people to use HTML5 instead of Flash for similar reasons.
