What is a good app for image triage?  When I say image triage, I mean something that will:

• Read images off a storage card (I generally don't use USB/Camera cables)
• Allow me to quickly decide whether I wish to keep an image or not
• Rename and file the picture into a directory

Currently, I use BreezeBrowser. It's pretty good, and it reads Canon .CRW files.  If anyone has a better app recommendation, let me know.  I have a Canon Powershot G1 (main "art photography" camera) as well as a Nikon Coolpix 3700.
