Christmas for geeks comes in January, as we're in the midst of both MacWorld and CES. Google's gift for us today is Picasa for Mac [1]. It doesn't matter if you're already using iPhoto or Picasa on the web, Picasa for Mac is a seamless companion.

Its standout features are the photo management and organization, as well as its editing abilities (including the genius ways Picasa preserves your original files, post-editing). Want to see it in action before you download? Check out this video demo.
