Here’s is a cool app for Vista that allows you to tile your open windows on the desktop just like Expose on a Mac.  Your PC must be capable of running Vista Aero to use this app.

An issue came up where there was a locked directory on the desktop of a Mac running OS X 10.4. I couldn’t delete it from the terminal either. Here is the way to change the attributes so you can delete (or move to trash) it successfully.

1. Open Terminal (/Applications/Utilities).
2. Type this, followed by a space: sudo chflags -R nouchg
3. Drag the folder you would like to unlock into the Terminal window.
4. Press Return.
