Load Up Your PC

Ubuntu (www.ubuntu.com)
Have a new PC? Now you need an operating system, and that can run up to an additional $278 for Microsoft's (MSFT) Vista operating system or up to $200 for Apple's (AAPL) Leopard. The Linux-based Ubuntu operating system is free and comes with a word processor, spreadsheet, presentation software, browser, e-mail, media player, and photo-editing software.

OpenOffice.org (www.openoffice.org)
The basic version of Microsoft's popular Office suite runs as high as $400. There's no charge for OpenOffice.org, and it's available for Windows, Mac, and Linux.

Pandora Recovery (www.pandorarecovery.com)

Libra (www.getlibra.com)
You get a simple way to organize your collections of books, CDs, DVDs, and console games, and Singapore developer CodeJam gets affiliate revenue from e-commerce sites like Amazon.
