With more than 250 000 free downloads, Cobook the alternative address book and contact management system for Macintosh computers, is ready to move on. As reported on TechCrunch, Cobook is now offering version 1.1, which syncs with the user's Google contacts. In his talk with this blog, Kaspars says there are plans for an iOS (iPhone and iPad) version of Cobook, eventually an Android version, and, somewhat sooner, a paid version for some consumers and for businesses.
