There are several things you can do:
1. Windows Live Gallery
- This is the note gadget for windows gadgets.
2. Use Google Dekstop
. I trust my life to this thing, and when you double hit CTRL, you can search your entire computer in seconds (a bit like the spotlight in mac)
. I use this thing all the time. It has keyboard shortcuts for easily creating a new note.
(4. Yahoo Gadgets) I don't like this one, but it works and you have a "Dashboard" mode, maybe even more useful.
