Difference between SP 2013 Preview development environment and SP 2013 Server Preview

Question

Just going through few projects provided by Microsoft for sharepoint 2013 developers I seen requirements for development tools, it says

This sample requires the following:

Visual Studio 2012 SharePoint development tools in Visual Studio 2012 A SharePoint 2013 Preview development environment

I installed sharepoint server 2013 but my laptop only has 4 GB ram so I couldn't test it much, how can I test developed sharepoint 2013 apps/solutions by me and if I can develop them without having sharepoint server.

Answer 1

For non-code solution(infopath and SharePoint designer workflow) , you can use the office365 preview.

If you need to use Visual Studio then you need to have a development environment,you should upgrade your computer or looking for cloud solution like CloudShare
