Steve Jobs has been vindicated yet again. His April 2010 letter explaining Apple’s decision to forbid Flash on its mobile devices has proved to be a death knell for Adobe as almost 18 months later, the software company will reportedly cease development on mobile Flash and instead increasingly invest in HTML5.

Adobe will continue to support the Android and Playbook configurations of Flash, but only with bug fixes, not software updates. Desktop configurations will live on.

The move by Adobe isn’t a total shock, as the company rolled out Wallaby, an experimental tool converting Flash to HTML5, back in March.
