Flash is not supported by most mobile platforms

Most experts predict that mobile platforms will occupy a significant portion of the internet browsing in the near future. Currently, Flash is not supported on many of those mobile devices, including the iPhone and Blackberry. Basically, developing a site in Flash ensures that you are not thinking for the future.

Most Flash effects can accomplished using better methods
