Mac Text editors

Hi everyone,

I've recently moved from using a windows machine to a Mac (some might
call it an upgrade, others not?I'll let you be the judge).  Once I
started using Notepad ++ on my windows machine, I really began to 
like
it.  Unfortunately, I'm not sure what the free text editor options 
are
for the Mac (Notepad ++ is windows only).  I've dabbled with Linux
before and used Emacs/ESS there.  However, I seem to remember 
fighting
pretty hard to make that work and the OSX file structure isn't that
intuitive to me yet.  (For example, where is my .emacs file?)

What text editors are best for the Mac, keeping in mind that I'm
probably going to use them via the command line interface (e.g. X11 
or
Terminal).

Thanks!
