Phatware have just released their latest version of their notes organizer for Microsoft Windows-based Desktop, Tablet, and Pocket PCs.  PhatPad allows users to draw pictures, jot notes, or put a mixture of pictures and typed text on a virtual scratch pad.

I used to use PhatPad all the time but since I've got OneNote Mobile 2007 I have moved onto that... it's still a great application though if you aren't running Office 2007 (yet).
