iSkysoft offers downloads of its iSkysoft Video Converter for Windows and Mac for free. (You'll have to sign up for a free keycode via this link.) That's tied with last year's mention as the best deal we've seen for this software, which converts AVI to MPEG, WMV to MPEG, WMV to MP4, and more. It supports such devices as Apple iPad, iPhone 4, PlayStation Portable, and Microsoft Zune. Deal ends January 5.
