Do you need Word 2013 for integration b/w desktop & web app?

I haven't fully plunged into Microsoft's OneDrive, as I'm very happy with DropBox.
But one feature of OneDrive caught my attention, which I think potentially can open a lot of possibilities: integration between their Web App and desktop app. It lets you open an Office document stored in cloud directly in a desktop application.

Well, conceptually, at least, because it doesn't work with Office 2003, and OneDrive's help also says you need the latest Office.
Does that mean I need Office 2013 to use the Web App protocol? Is Web App as good as it looks on paper? Any pitfalls that anybody experienced?

The Office Web Apps (now called Office Online) are nice for viewing documents and workbooks, and perhaps for basic editing, but they are very limited compared with the desktop Office applications. I personally think they're not really useful.

They work in your browser, you don't need to have Office 2013 installed.

No, I have no intention of using the Office Web Apps. Like you said, they are rudimentary. That's exactly why I'm trying to open the cloud document in desktop application through the so-called "seamless integration" between Web App and Desktop application. Below is the error message I get when I try to open a cloud document in Desktop application.

I don't think that will work with Office 2003.
If you want to edit a document stored on OneDrive, download it to your PC, edit it, then save it and upload the document to OneDrive again.
