Paul at a crank’s progress notes that Microsoft is doing away with the “My” prefix:
Those folders on your Windows desktop will still be yours — but in the future you’ll need to figure that out on your own.
Ending a longstanding tradition, Microsoft Corp. plans to stop using the word “my” as the default prefix for such folders as “My Documents,” “My Music,” “My Pictures” and others along those lines. Starting in the next Windows version, due out next year, folders will be known simply as “Documents,” “Music,” and so on.
He suggests that it will seem a lot more like Apple.
Or it could be that once Microsoft includes DRM in Office 12, the word “My” would be false advertising because your documents will now belong to Microsoft Office.
