Who knows a nice NOTEPAD app for Windows?

Can anyone recommend a nice notepad type of app that you can snap to the side to take notes? (Including basic features such as bullet lists)

(I use OneNote a lot, and need another app to take side notes next to OneNote. Unfortunately you can't open a second window of OneNote.)

This is what I'm currently using: http://apps.microsoft.com/windows/en-us/app/writeplus/486f8570-1758-4563-b89f-c8923f50182d It pretty and has some advanced formatting features, but it has some flaws (such as weird bullet list behavior).
