Get yourself TextPad, right now. The user experience will be a seamless upgrade from notepad, just about a million times better. You can get into a "which editor is best" flame-war on down the road, but if you're coming from notepad, textpad is gonna be the easiest upgrade path for you to a real text editor.

Update: Yes, I do recognize the irony of pushing textpad in my post while my sig makes specific reference to vi. Life goes on... I'm recommending the guy use textpad because I think that's what'll help him out the most right now.
