To be honest, I hope they never "improve" Notepad (either of them: http://blogs.msdn.com/oldnewthing/archive/2006/03/28/563008....). I think every operating system needs a totally-bare-bones text editor. Because of that, I think Notepad does exactly what it's meant to do, and "improving" Notepad would change that.
WordPad, on the other hand... They can keep Ribboning the shit out of that for all I care.
