I did not use the Google Picasa for managing my photos on my PC. But new Google Photo Apps is really attractive for me to use as main photo managing software.
Google announced their new photo managing software at their conference on 5/28. The new Google "Photos" allows us to use it as Free as long as the photos are untill 16M px and the videos are 1080p formats.
I think this is great to use as Free even the file size is limited, especially for the person who do no use iClould because of its cost. I will try to use this software immediately.
