Somebody in Windows team impressed with Tomboy Notes (Linux) application or PNotes (Windows) application. They decided to add this to Windows 7. If you have touch screen, you can write down information on the notes for quick jot down. These sticky notes are really simple has only two buttons on the top (Close and Add new notes).
If you have Windows 7, you can check this out by clicking Windows Orb button and select “Sticky Notes”.
I am using PNotes in my XP Laptop for a while and I am addicted to it. PNotes is free and you can get it here. It has all the bells and whistles you would expect. You can download it by clicking the image below:
