Cloud storage service SugarSync ( a service like DropBox or Box that has folder syncing capabilities) has updated to 2.0 Beta which greatly enhances the experience. I use SugarSync as it was one of the first to offer folder syncing, but now it is much better with drag and drop, easier sharing, cloud search or as SugarSync Drive from the finder, and it has a greatly enhanced Photo gallery. SugarSync starts at $49.99 a year for 30GB of storage. You can check out a video here.
Hopefully they will update the iOS app soon (Android is first).
I kind of wish that the desktop app was just in the widget in the menu bar instead of running an additional app, but it is a powerful app, especially for easy sharing.
