True, but with Google Docs the uploading step is extra; you can open files and save them right inside the file open/save dialogs in Word and Excel if Sharepoint's setup properly.

If something could map say a "My Google Docs" folder under My Documents it would be the same; so you can just go into Word and open a file up for editing.

Personally I'd rather just open my browser, but hey I've used several word processors as well :P
