There are desktop clients available for syncing data directly from PCs running Windows, OS X, or Linux as well as mobile apps for iOS and Android devices. More importantly, stored data can be accessed using the ownCloud web frontend in any standards-compliant web browser. Any updates to files are pushed between all computers or mobile devices connected to a user's account.
ownCloud has been accepted into the Debian GNU Linux repository, and has been integrated with the GNOME desktop. Recently, integration of ownCloud with the Kolab groupware and collaboration project has been commenced.
Additional projects that use or link to ownCloud, including the RaspberryPi project from Cambridge (UK) which supports a cloud storage solution using its tiny and low-energy hardware platform.
