As a developer, I steer clients away from relying upon Flash for anything on their site. Adobe would love Flash to be the medium of choice for everyone but the truth is Flash doesn’t bode well for deep linking, navigation is often slow and clumsy, and it is not as portable as straight HTML to mobile devices and other non-traditional browsers. Granted, Opera mini, other tools, and Adobe are trying to make Flash more readily usable on all platforms.
I do like Flash! I think it should be used to enhance the overall user experience on a website. Perhaps certain navigation elements could be done in Flash but if the browser cannot detect the Flash plugin then it shows a regular HTML navigation. Keep it small and light. Now, all that aside, the Sony Bravia Flash site is cool! And just when I was getting comfortable with the 2D web, someone had to go and add depth.
Ah! I put my finger on it as I was commenting at ProfessorFalken:
It adds the z-axis to browsing to bring us closer to that 3 dimensional hokeyness we see in computer movies like Hackers and Johnny Mnemonic. [Source]
