Why HTML5 sites for mobile require a mobile specialist

Although several mobile browsers now support HTML5 this is a version of HTML5 adapted for mobile:

A.      The design and user interaction of a mobile site is completely different to its equivalent website.  The use of the touch screen, the smaller screen size, different usage occasions and scenarios require a user experience designer with experience in mobile

B.      The browsers vary significantly depending on the OS – for example iPhone vs. Android but also between different Android devices.  Resolution/ screen size and layout (landscape vs. portrait) may differ from device to device

C.      The functionality of HTML5 on mobile devices can integrate parts of the native functionality such as location, messaging, contacts, accelerometer, etc.

D.      Each OS requires particular encoders for video

E.       Android in particular has differences depending on the OS version (1.6, 2.1, 2.2, 2.3 and soon 3.0) which means that the mobile site needs to be tested across all device versions

In summary there is currently not one version of HTML5 but several. For a mobile implementation of HTML5 you need someone with experience in mobile development. Before there is a stable development standard for mobile sites, there is still a lot of standardisation work remaining.
