Dropbox is already the dominant cloud storage provider, and now it has a new goal: being adopted by developers to store data that isn't in a traditional file format. Its newly-released Datastore API lets mobile app developers store information for their apps and have that synced through the existing Dropbox service.
Dropbox has also launched two new 'drop-in' code segments, Chooser and Saver, which make it easy to allow users to access existing files in Dropbox or save files to their Dropbox in other apps. Chooser is now available for iOS and Android (a webapps version was released last year); Saver is available for webapps, with mobile versions promised in the future.
