CX: Good sync product, doomed market
But Dropbox, SugarSync, CX, and all the rest are zombies. In a short time, I'd guess two years, the world won't need file sync software at all. Because the whole concept of using software to create and store files on a local machine is becoming anachronistic. More of the apps we use store their data in the cloud, so it can be retrieved by a user as he or she moves between computers and mobile devices. Look at productivity apps: Apple's apps (like Pages) sync via iCloud. Google Docs is all Web-based by nature. Even Microsoft's Office apps (like Word) can save to SkyDrive, and Microsoft's new Office 365 is a direct competitor to the Web-based Google Docs. For new files, who needs local storage for anything but cache and occasional disconnected use? Many great new productivity apps, like Evernote, don't even expose their local file storage to users at all (unless you dig). These apps--there are others--inherently store user data in Web servers, replicating it to local storage when needed.Other traditional apps, like Quicken, are aging out, being replaced by cloud-based services like Mint (from the same company, no less).The last data types to need local storage are media: books, music, photos, and videos. Books are already cloud-stored. Buy a Kindle, connect it to your account, and it downloads your books as you need them.Music is moving into the cloud rapidly. Apple's iTunes Match (when it finally launches) will go a long way towards freeing users from having to worry about storing their music. Furthermore, more users are moving to leasing access to streaming music libraries (look at Spotify and its competitors).Photos, then? Yes, you need local storage to keep a photo library. But maybe not for much longer. Again, Apple's leading the way for consumers: Take a photo on your iPhone, and it's synced automatically to all your Apple devices. Apple doesn't provide archival storage for photos yet, but give it a few years. Videos will be the last data type to tie consumers to local file systems, but I wouldn't bet against falling storage and bandwidth costs for very long. The whole idea of needing to manage local storage is dying.There will be holdout apps, of course. A lot of them will be products critical to business, like design and engineering apps. There is a big opportunity in providing cloud storage and local sync, at a system and API level, for these apps that don't have it already. Developers will need to revise apps that use old-style file storage systems to take advantage of cloud-based storage with local as-needed sync services. Fortunately, that's also the long-term vision for CX. "We're the grid," the CEO told me, when challenged on this topic. I believe the Bitcasa team also gets this; I know Dropbox's does. It's in building Internet-based file system back-ends where the interesting battle will be. But the market for end-user file sync and sharing, no matter how fast it grows in the next few years, is speeding straight into a brick wall.Rafe's rating: CX.comProduct quality: Four out of five stars. Strong, competitive file sync product with outstanding sharing tools. 10GB free storage, reasonable rates beyond that. iPhone, Android apps still in development, and no word on Linux support. Business quality: Two out of five. Despite a currently growing market for file sync tools,and even with good features, the steamroller of sync built-in to Web-centric and mobile apps will kill this market. There is potential for a business to be built around back-end file and sync services, but look to Amazon, Google, and current darling Dropbox to be serious competitors in this space.Note on the Rafe's Rating scores: These are solely my opinions, informed by my experience reviewing consumer technology products and covering startup companies over the last 20+ years.
