Very cool: Google's Picasa client is now available for OS X
Before I switched my business over to using Mac OS X, I "lived in Linux" and very much enjoyed the Linux port of Picasa. I use both Picasa and Flickr: both very good in different ways but I will favor Picasa now that there is a Mac client program. I enjoy travel, friends and family so reviewing pictures and videos is an almost daily activity. Picasa 3: highly recommended!
