Pocket PC/SideWindow

SideWindow has a killer description that immediately endeared it to me: "FINALLY! The expensive desk ornament that used to be your cradled PDA can now serve a useful purpose. SideWindow transforms your PDA into a virtual desktop extension, allowing you to drag applications such as your favorite picture viewer, media player and instant messaging applications to your PDA while freeing your main display's real estate for something more useful.
