Switching to Notepad++
When programming on a Windows PC, I use Metapad (http://liquidninja.com/metapad/) as I have for about a decade. (I used EditPad Lite prior to finding Metapad.)
Recently at home I have been using Notepad++ and it's really grown on me. I've always liked having all of my open documents in tabs. It also has syntax highlighting which really helps me see mistakes before I've even tried a compilation check.
I'm going to install it on my work laptop and see how it works out for me.
