Adobe's Flash and Flex are still relevant in the web development landscape despite Apple's support for HTML5. The massive installed base of Flash on 98% of computers ensures its continued use, along with comprehensive tool sets that developers need. While HTML5 has its advantages, it cannot yet match the capabilities of Flash in areas like webcam capture, media-streaming, and full-screen video. The Sauce Labs announcement of the Sauce Flash-Flex Testing System addresses this gap by providing testing of Flex applications on the Flash platform, catering to the large market of Flash-based gaming and advertising.
