I currently use Office 2013 and I'm confused about what Office 365 actually provides. I know about the storage and the license for Office 2013. Do you get better versions of the web apps when you subscribe? Word online is a bit unusable to me without an equation editor, as nice as it is to collaborate online. I'd like to be able to access the full power of Office 2013 on whatever device I'm using - is this possible with Office 365?
