PC World Freebies Software

Lifehack.org had a posting about the 101 Fabulous Freebies from PC world.
Looking at the list, actually I've been using quite a few of those already---
Google Earth, OpenOffice.org, Skype, Gmail, Blogger, Bloglines...

I put a link here for my future reference.
You can also check it out yourself to see which freebies software you like.
