From the article "So on Tuesday, all of CodeWeavers products, which allow Mac and Linux users to run Windows applications, can be downloaded for free -- instead of $40 each -- at the company's website, www.codeweavers.com."
However, the rules for the challenge on their site say "If a Lame Duck Goal is met by the 28th of any given month, we'll give away our software on the first day of the following month. For 24 hours. Free copies of all our software products. Fully functional, fully supported. The real deal. One copy per customer. If more Goals are met, we'll give away more free software."
Keep your eyes peeled.
