Microsoft recently posted a link to some free (and paid for the Pro edition) Tablet developer tools. If your looking to add Journal like features to your apps, this is a quick and easy way to get there.
Agilix InfiNotes Tech Preview Release
Agilix InfiNotes(TM) is a RAD note-taking framework for the Tablet PC Developer. Shorten development time by dragging Journal-like note-taking capabilities into your existing applications rather than writing this code yourself. InfiNotes installs and integrates into the Visual Studio 2003 environment and is available from the ToolBox Tab. For more information or to download the free software, please see www.infinotes.com. To read more about InfiNotes, see Adding Journal-like Functionality to Your Ink-Enabled Application.
