Well, Picasa 3 beta is already ready for download and i must tell that there are 2 Most liked things in this update :
1. Picasa Viewer : Works fast, click on an image and navigate throu the photos in the current folder.
2. Picasa Web Albums uploader. I like this Button : ” Dont eat my bandwidth” 
so if you are ready to try it , i had to tell these two features i really liked.
