I've blogged previously about some of Gil's great FREE applications.

SpooNotes is a note taking application for quick handwritten notes.

• Different pen width and color
• Different notes colors
• Smart writing surface:
• Auto-expand option (while writing!)
• Easy navigation through the note
• Unlimited undo
• Zoom options
• Save notes as jpg’s or png’s
• Open from list, browse thumbnails, etc.
• Send notes via mail
• Pin notes (popup when device turned on)
• Picture notes (take a picture and write on it!)
• Screen orientation
• Invoke from phone call (shortcut appears when talking)

Best of all it's free so if you think it could be useful - check it out HERE
