SMEs in the cloud

Some interesting research from Box.net on how their customers use their data hosting service seems to indicate that SMEs (or SMBs as they tend to be called in the US) are embracing cloud-based services like Box and Google Docs/Apps.  Of course the survey is biased as it only included Box customers but over half of the 8,000 people surveyed use Box in conjunction with Google Apps and Docs while 13% use Box with Microsoft Sharepoint.  According to Box, their service is often used by Sharepoint users because it makes sharing files outside the enterprise easier by getting round firewall and permission issues.  The graphic I've taken from the research report (also available as a PDF) shows the, not surprising, inverse relationship between company size and use of Google Apps/Docs and Sharepoint.
