I suppose MS needed to keep something in the old locations for
compatibility with old badly coded apps, although why MS thought it'd be a
good idea to move everything about for the sake of it is a mystery to me
Two words: Simplification and Security.
For the first, getting rid of "My" <everything> was a response to a lot of
negative feedback. Other things, like D&S were overly and unnecessarily
long. The UI, for the user, is all about each simply having their own
desktop, folders, and applications. Nothing complicated.
For the second, moving applications from running in the system environment
to the user environment is quite a feat. Not only new applications designed
for Vista, but redirecting older ones to run in a virtual directory as well.
A lot had to be built in to the system for this latter event to happen,
otherwise users would be limited to only Vista compatible applications.
