I've never used CSS before and to be honest viewing a CSS page in DW is un-inspiring.
Looking at examples of CSS on the web, I feel as graphic representations disappoint, in that icons move around making me feel a bit sick adding possible negative connotations. With framesets I can design buttons, add video, design flash banners or even add key command 3D engine object movies enabling the user to pre-visualise the product. As a pre-requisite I need to see the end product before investing time and effort and because of a need to self manage I choose framesets. Unless I can simulate the framesets registration design, like fixed top or fixed left and add flash buttons with movies is it possible?
I've taken a look at Apple's site and I too cannot find any framesets. You must be talking about something else, not what we understand about framesets!
Anyway, that on one side, it is possible to place anything and everything within a pixel breadth on a website page with CSS. What a pity this conversation didn't materialise a couple of weeks back. I could have recommended that you visit Sitepoint.com and join their css presentation for a very worthy and cheap price, to learn css. I'm sure they'll run other such tutorials (video and text) in the near future.
Hope this helps,
