Right, but with the disadvantage of not having a free version, and they still have the same downside as Google Docs, which is that your cloud-hosted data is accessible by the NSA, who may then share it with other government agencies.

On the other hand, as soon as you e-mail an Excel spreadsheet outside to anyone outside your corporate intranet, the NSA can see that data too, if they want.
