Is it? Is it really? As far as I can tell it is simply a cloud-hosted distributed platform (not decentralised and certainly not innovative) of office-style apps bundled with an Ethereum fork rebranded with the Ethers renamed to DEOS.
That is what the demo looked like but from what I understand by all the docs I have seen it is more like ethereum but with file storage and sidechained with bitcoin.
here is an interesting page on the razorcoin/mind site:
