CX (free to $19.99 per month) is a cloud-based syncing and storage back-up solution, similar to the well-known Dropbox, that gives you access to your files from virtually any Internet-connected device. CX offers free downloadable software that works seamlessly on Windows and Mac, as well as free apps for the iPhone, iPod touch, and iPad. Where native apps aren't supported—and they're notably missing from Android, BlackBerry, Windows Mobile, and Linux—a straightforward and responsive website, CX.com, stands in just fine. In fact, in many ways, I prefer the online dashboard to the apps because it supports a few additional features not found in the software, such as threaded comments between collaborators.
PC Magazine Reviews CX’s Cloud-Based Syncing and Storage Back-Up Solution
Getting a CX account takes little more than a trip to CX.com and signing up with an email address and password. New users start out with a generous 10GB of space, although CX states that this amount is = a limited-time offer. Still, it's absolutely worth snagging if you're in the market for a syncing service, as it doubles SugarSync's 5GB, which is itself more than double the 2GB offered by both Dropbox and Syncplicity.
CX's online dashboard, which is where most users start their experience, is extremely easy to understand and navigate. The elegant online dashboard shows a list of recent activity, all time-stamped. Tabs for files, groups (for collaborating), favorites, and your profile are as straightforward as they seem. If you're new to file-syncing, the website is by far the simplest place to get started syncing and backing up your files.
Perhaps the feature that most sets CX apart from its competitors is commenting. If you use a cloud-based syncing service for collaboration, commenting on a file to discuss it, rather than allowing multiple people to alter the file, may be a considerable part of your workflow. Comments only appear in the online version of CX, further highlighting the utility of the website version. Comments are even more effective when users upload their profile pictures, as each comment appears alongside the profile photo and username of the person who wrote it.
