Interesting. AVG, well known as a malware fighting company, is launching a competitor to Dropbox called LiveKive. Essentially it looks the same. Store your data with LiveKive and sync it and access it or share it from any device you’re using. LiveKive’s pricing structure offers you 5GB for free, 25GB for $49.99 or unlimited for $79.99.
Obviously there are other competitors for your cloud storing/syncing/sharing needs like SugarSync, Box.net, etc… but to say it is a crowded or a well defined market is probably premature. That said, the real question I have about LiveKive (and other Dropbox competitors) I have is will, or do they provide an API so that other Apps on mobile devices can take advantage of the files in the cloud.
Of course there is already an iOS App to access your LiveKive.
It's my life, you're just along for the ride!
