Some OS X stuff:

Print your own book using iPhoto (rather than pay Apple).
Some iTunes scripts, including one to speak the name of the currently playing song.
SlashDock headlines tool for docking bar. Allows seeing new headlines/articles from sites which support RSS feeds (like this one...click the XML logo in lower right corner)
You can drag your hard drive(s) icon into the dock. Then, when you click down on the new dock HD icon you get a heirarchical interface to your folders.
You can also shift-click on your dock to move it to other edges of the screen.
