Running Vista; My Documents
Ranting coming up, you might want to skip ;-)
This is not actually a Vista problem, but a Windows problem. Why is the My Documents (or in Vista: Documents) folder so abused? Just take a look at what's in mine and note that I'm not actually saving my documents in there.
Why are all these files/folders in there? Isn't that an "Application Data" folder somewhere? Why do I feel I need a "My actual documents" folder in there? Maybe I need a little tool that transfer everything that's not actually mine, into some other folder.
