My votes are for EditPlus (http://www.editplus.com/
) and Notepad2 (http://www.flos-free...are.ch/notepad2.html
). I use a ridiculous number of text editors on pretty much every platform I use, because as simple as text editing seems, it's actually very personal and difficult to please everyone with one editor. Holy wars abound in the Unix world over vi versus Emacs (to name perhaps the most long-standing battle), but similar conflicts are also present in the Windows and Macintosh communities too.
I can rant on and on about why I use so many text editors and which editors remain my "default choices" for which tasks and on what platforms, but I like EditPlus (as my favorite Windows-native text editor) for anything more than just writing a quick, short plain text file or looking at a simple, uncomplicated plain text file. I often use Notepad2 (which I've assigned Ctrl-Alt-N in KeyText for launching it) to write down little notes or URLs or to view README files and the like, which litter my home directory and its subdirectories. EditPlus is the best "full-featured" Windows-native text editor I've found, and the one I keep coming back to despite having tried easily over a hundred other editors. I've been using it since at least 1998. While it has a number of built-in features for web developers, such as the in-editor browser, I don't make much use of that. I do use it to edit HTML and the like, but primarily I use it for programming, etc.
I found Notepad2 sometime in early 2004, if I recall correctly, and have been using it as described above, since then.
If I were to pick just one editor to win the award, I'd pick EditPlus.
I have a occasionally-updated text file which catalogues my notes on using various text editors over the years, though I didn't start putting it together until a few years ago. I had planned to make it into a large article or essay for my web site, which I may still do. The idea was to capture what I did and didn't like about the editors I was using or just trying out. Chances are, if you can think of a text editor for Windows, I've at least tried it.
Just in the interests of, well, I'm not sure what, here's a list of some of the editors I use on Windows besides the two mentioned above, in no particular order:
GNU Emacs: http://www.gnu.org/s...are/emacs/emacs.html
Programmer's File Editor (PFE): http://www.lancs.ac.uk/people/cpaap/pfe/
