Watch this CNET TV video on the best downloads of 2007. Hearteningly, OpenOffice tops them all: Open-source, free, and compatible with Microsoft Office formats, OpenOffice offers word processing, spreadsheet, presentation, and database capabilities.The top five winners are—

1. OpenOffice
2. Audacity
3. Miro
4. Pidgin
5. CrossLoop

Nice to see the instant-messaging tool Pidgin on the list, too. It works well!
