Steve Jobs has posted an open letter basically claiming that Apple has moved on from Adobe‘sFlash for their iPad, iPhone and iTouch.

It appears that the company is not interested in providing Flash compatibility on those devices because Steve Jobs considers this technology to be antiquated and less secure in comparison to H.264 and HTML5.

Furthermore he claims that if Flash were implemented that the software required to decode older Flash material would drain resources in these devices, resulting in a significantly reduced battery life.

Shantanu Narayen, Adobe’s chief executive, responded to these claims on a Wall Street Online video.
