iPad Forcing Web Developers To Use CSS3, HTML5 and Open Standards
The iPad's (and iPhone's) lack of support for Flash has been a hotly debated topic among developers. Developers who want dynamic content such as videos and animations on their website had to create it using the next generation markup languages that the W3C has yet to classify as formal specifications.
According to Google search results, there are at least 74 million websites that are using the Adobe Flash format to display video and animation. Developers are already complaining that the tools that are available for HTML5 lack the advanced functionality that Flash tools currently have.
