I would like to sync my photos so that I can see them on my phone, tablets, however I don't really like to have them actually all on my phone since storage is limited.(just like dropbox and other cloud services) Also on my phone or tablets, it is really hard to know which photos I am looking for when file names are most likely DSGxxx, IMGxxx without thumbnails. Maybe for people who wouldn't need this, it is always good to have a checkbox for options.
