"We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil" Donald Knuth

Flex Hero
“Slider” was originally planned to be a separate version of the Flex framework that would contain mobile-specific functionality. However, due to the evolution of the mobile device landscape, as well as significant performance improvements in the latest releases of the Adobe® Flash® Player and Adobe® AIR® runtimes, it is now feasible to integrate these mobile development features directly into the core Flex framework. As a result, the mobile features that were originally planned
for the separate “Slider” framework will now simply be a part of the next version of Flex, code-
named “Hero”.
