I despise frames. And let's call these fixed elements what they really are: frames. In addition to reducing the usable screen area (which is awful on my netbook's 1024x600 screen)[1], frames also break the page metaphor. Part of what makes the web easy to use is that interacting with each website works more or less the same. That is to say, the scrolling behaviour of web pages mimics a real-life piece of paper. If the entire website no longer scrolls as one uniform page, when visiting a new site, the scrolling behaviour is unpredictable with each site doing something different. My terminology is clumsy, but perhaps it is clear enough to understand what I mean.
