The main difference between DeskNotes and other note utilities is that DeskNotes is designed to be used as replicants. This means that when you tear a note from the DeskNotes application onto your Desktop, it stays there! You don't have to save it before rebooting, or fiddle with your UserBootscript.
You can choose different colors from a right-click context menu or drop arbitrary colors from applications like 'Icon-O-Matic' or 'Colors!'.
And, even as replicants, notes can be resized with the bottom-right resize widget.
