PDF 2 PSP is a simple tool for converting PDF documents and printouts into JPEG images suitable for displaying on the Sony PSP handheld game console. This allows you to download e-books, game manuals, album liners, etcetera to your PSP. Once they're on your PSP, you can read them anywhere. Because of the extensive PDF support built into OS X, any document you can print can be stored as a PDF and converted and downloaded to your PSP. It works best when used with a PSP synchronization tool such as PSPWare, but it can also be used as a stand-alone tool.
PylotLight is a cross-platform, themeable, plugin-supporting system for general computing tasks. It is comparable to QuickSilver, which you may recognize if you use a Mac. Current plugins exist for Web searches, Firefox bookmark launching, filesystem browsing and managing, subversion control, terminal control, and more.
If your Mac is ever stolen and Mac Calls Home is installed, it will inform you of its location by using an existing Internet connection. It will try to send as much information as possible about the location, and if an iSight camera is available, it will snap a picture and send it to you as well.
