Good idea. All websites should have more content and less flash (and Flash).
Whenever I go to websites that have fancy intro, I immediately hit the back button. It makes absolutely no sense for the company to waste bandwidth and development effort for something that will in the end annoy the customers. Fortunately, I think many of the companies are learning and using Flash and animated gifs in a much more judicious manner.
One more thing. Please remove that annoying "click" sound when the menu is selected. Thanks.
