Thanks everyone for point me into the right direction. I guess the default behavior of vim is what it is.

Curiously, if the file permission is 644 and the file belongs to root, then a normal user does not even need sudo to override readonly, just use :w!. (and in addition, the ownership of the file would change from root to the user.) Whereas this is not possible in nano, i.e., only root and sudo have write permission in 644. Does anyone know why is this?
