I've worked in a company using windows for a while now. I've tried a few editors. I'm not a big fan of context, but Edit Plus and XEmacs work very well. They all have syntax highlighting, etc. I still prefer gvim for windows. It support windows commands(CTRL-C, etc.) and VI commands. It has a steap learning curve if you haven't used vi, but it is extremly powerful once you learn the basics.
