If you are a Flickr user and have an idevice this is a necessity.  This app and a camera connection kit could elevate the need to take a laptop on a trip just to upload pictures to flickr.  After a few days of light use I have found ways to use Explore more effectively and the big one is to upload.  Obviously the need to edit and watermark are still there but in  a pinch this will work and will save time and your back on the quick weekend trips where the iPad is all you need.
