I really wish companies would separate their marketing and customer support web pages, and avoid all dynamic elements on the latter. With only a few exceptions, animation, pop-ups, scrolling within frames, and other supposedly eye-catching techniques only tend to slow down the current customer who is engaged in a focused attempt to get information or assistance. And despite purported standards conformance and client-platform recognition, my experience is that some things which work fine on desktops can be flaky when used on mobile devices, and vice-versa.
