We're big fans of Office 365, use it to run our business and have been pleased to see OneDrive for Business get better and better – even unlimited storage for Office 365 subscribers will be with us soon.

We're often asked about the differences between OneDrive for Business, SharePoint and "plain old" OneDrive, this blog post from Microsoft is a good answer to that question.

Another useful place is the Office 365 Roadmap. Using "OneDrive" in the search option will show you what is in the pipeline for the product and what new changes are already available.

A particular issue for OneDrive for Business is that certain characters that are valid within a filename on your PC (in particular # and %) cannot be used if you want to store a file with that name in OneDrive for Business.  Full details can be seen in the following Microsoft support article.  The good news is that the fix for this is in development which will make the move to OneDrive for Business and SharePoint Online even easier.
