I've been using TextPad ever since it came pre-installed on my school laptop 5 years ago.  The program is very simple and easy to use.  It's basically just a text editor, but its most significant feature in my opinion is its right-click integration.  You can right-click on pretty much any file on your computer and open it in TextPad, whether it's a text file, an html/js/php file, an exe file, or a jpeg file.  Really anything. 

One problem that I encountered and have been dealing with is the fact (or so I thought) that you couldn't turn on word wrap by default.  There's a little button on the toolbar that does it, but I always had to click on that to enable word wrap.  But then I found this link that said, "Click on Configure > Preferences.  Under 'Document Classes' on the left, click the '+' button and then choose 'Default'.  You should see the default preferences for files show in the right-side of the pane.  Make sure 'Word wrap long lines' is checked and hit 'Ok'."  I tried it and it sort of worked, but I fooled around with it and found that if you make sure that the box is checked for each of the document types, it'll work all the time.  So that's what I did and it worked great.
