The Windows Taskbar and OS X's Dock have gone through a few changes over the years. But despite their evolution, at the core they are still all about being able to quickly launch your favorite or most frequently used applications and easily switch between open windows. With that in mind today we want to ask you: what programs do you keep pinned to your taskbar (or dock for Mac users) and why?

Feel free to include a screenshot with your comment (you'll need to switch to forum mode). Mine is posted above (OS X's Dock) and includes Reeder to check my RSS feeds, Safari and Chrome for browsing, Transmit to upload files to the server, Pixelmator for some light graphics editing, HipChat for our internal communication at TechSpot, Things to keep track of to-do's, and Apple's Activity Monitor and Mail.
