Who says there's no such thing as a free lunch--or free software? Giveaway of the Day gives you exactly that (the software, not the lunch), offering a different free download every day of the week. These aren't the usual open-source suspects like OpenOffice and GIMP, which you can get anywhere, but rather full-function, unrestricted commercial products that would normally cost you some coin. For example, today's freebie, a disc-cloning utility called Keriver Image, normally sells for $15. A few days ago, the giveaway was Aimersoft DVD Ripper--a $35 program.
What's the catch? There isn't one, but if you miss the 24-hour download window for a particular program, you're out of luck (though it does remain available for purchase, wink-wink). What's more, you have to install the program the same day you download it, otherwise the registration code won't work. Those are some pretty mild caveats, and while GotD won't land you a free copy of Adobe Photoshop or Microsoft Office, it's definitely worth a daily visit.
