In my earlier story on the business case for migrating from Google Apps to Office 365, I criticized both cloud products for their file storage tools: Google Drive and Microsoft SkyDrive Pro, respectively. Both need storage pooling and user quotas. But in the end, SkyDrive Pro is more disappointing.
The first thing to know about SkyDrive Pro is that it's not a professional version of the consumer SkyDrive offering, but a recasting of SharePoint MySites. Therefore it doesn't interoperate with the consumer version of SkyDrive, nor does it work with SkyDrive apps for iOS or Android, although there is Mac support. And if you have Windows Phone, you will have access to your SkyDrive Pro data. Check out Microsoft's "What's the difference between SkyDrive and SkyDrive Pro?" for more.
