Did a very short read about it. Interesting concept, whereas transfer of messages, files, etc go through "securely" on a private blockchain. Very interesting concept indeed, but we currently have no idea how "secure" that private blockchain is. Also, take in to consideration the usability of the phone itself. Correct me if I'm wrong, but I think it runs it's own operating system, and not Android. So even though everything or most stuff on your phone might be secure, expect a good number of apps to be uninstallable on this device.
P.S. That price though.

Never heard of any review yet, it is really that secure, has it been stress tested. Plus this is not for the masses, perhaps that target is more on a class, specially those businessman. And maybe most apps that will be deployed is for pure cryptocurrency used, like wallets. Let's see how it goes, but for me the price is very expensive. Well maybe that's the price you have to pay if you really wanted to be more secured.
