I LOVE Flash but discourage most of my clients from using it extensively. Search engines don't do a good job of indexing it. And I really dislike intros unless they are incorporated into the main site navigation.
At the same time, I think complete Flash sites have their place when glitz is the highest priority. And, if the budget is there, Search Engines can be fully accommodated with a mirror HTML website.
We just completed this site, and it is even over-the-top for my taste. We just could not have done this without Flash. Once we complete the alternate HTML site, it should do well with Search Engines too....

I agree that Flash sites do not have to take long to download. Stuffing them with video and music creates that problem. But there are lots of great uses of Flash that come from very small files.
