I have been using Notepad2 for a while now, and I really love it. I have never been a fan of bloated up and fancy IDEs, and so this should come as no big surprise. Notepad2 is very lightweight, has syntax highlighting for all languages I use, and has excellent keyboard shortcuts for most of the editing functionality. The only thing i miss sorely is the lack of tabs for editing multiple files at a time. Luckily Notepad2 is open source and is licensed under the GPL, and so i guess i can just add this missing tidbit. Let's see when i manage to find some time for this!
