Flash augments a Site very nicely. For visitor appeal it can go a long way, saying many words in motion, such as demonstrating how a product works.

Content depth and uniqueness are always going to be KING. Sure Google indexes Flash, but most Flash sites are poorly designed for the SEs.

An what about the need for "static textural internal links"?

IMO - Our only use for FLASH is augmentation like we used for this client (notice that we had to play some serious games to get the site to validate):

Why don't more developers mix HTML and Flash to serve both viewers and SEs?
