I am having some difficulty distinguishing exactly what is involved with Office 365 in particular when it comes to Office Web apps and Office 2010. It seems these are two very different versions of Office. Please comment on the following statements in the context of a small business scenario (not an individual usage scenario)
1) It seems that Office Web apps is a 'lite' version of Office that does not require any local installation of software - it is close to Google apps in that I access it through an URL.
2) If I want to duplicate the full Office 2010 feature set with Office 365 it seems I have to install Office 2010 locally albeit as part of the Office 365 package but at additional cost above and beyond Office Web apps.
3) What advantage/s benefit/s do I gain by doing 2 - installing Office 2010 locally and integrating it with Office Web apps - as opposed to just plain installing it locally?
