Flash the great cross browser technology... or is it?

Penguin.SWF: Stoppage

It seems that while the Flash plugin does offer a a way around those nasty browser bug issues you have to deal with in HTML, that rather than singling out browsers to mess up in, Flash ignores whole platforms. As it stands there is no Flash 9 plugin for Linux or Mac, there is a beta for Intel based Macs though, but some people are out of luck,

This isn't such a big deal until you consider Flex and it's prerequesite need for the Flash 9 plugin. So I think it is nieve to consider Flash the ultimate cross browser solution. It's right you don't have to tweak and faff around browser display, and early plugins do have good saturation - the latest firmware for the PSP offered (an almost) Flash 6 support. But if you are looking to use the latest versions you need to remember that you are completely cutting out some platforms.
