I'm not sure you understand what an IDE is. GoLive and Dreamweaver are not IDEs. An IDE, or Integrated Development Environment, needs to have, among other things, a compiler/interpreter and debugger: http://en.wikipedia.org/wiki/Integrated_development_environment Eclipse is an IDE, VisualStudio and XCode are also IDEs. They are generally used by developers, and any good web developer in this day and age is typically staring at either CSS, Markup, or Code of some sort. Designers clearly need a different environment. But for a good developer, writing the markup should be the easy part. Manipulating it reliably across environments, managing state, etc should be the hard nuts to crack. And notepad is not superior to a good IDE. A GOOD text editor (which notepad is not) is not superior to a good IDE. But I would certainly rather have VIM or TextMate or NotePad++ than plain old notebook if I can't have a decent IDE.
