Difference between Office 365 preview and sharepoint online
office365, sharepoint
Solution
The Office365 Preview is running on the new SharePoint 2013 platform. If you want to build and monetize apps/web parts, you would need to go with this option, as it is the latest and greatest.
Go to http://dev.office.com to get all of the resources you need including links to the software, tutorials, documentation, etc...
Microsoft provides a free Office365 portal specifically for developers who want to build apps on the online platform. With this, all you would need is Visual Studio 2012 and the SharePoint/Office SDK installed to build apps. You would deploy and debug directly on the online portal without needing SharePoint installed on your environment.
I hope this helps.
