Before I go off to do some Christmas shopping I thought I'd post at least the executable for the InkPad Sidebar Gadget I mentioned yesterday.
Here's a zipped copy of the gadget (inkPad.gadget.zip).
* To install the gadget you'll need Windows Vista RTM, which is available online for MSDN subscribers. I'm not sure the gadget will work with any of the beta versions. Let me know if it does.
* Unzip the file to the folder: \Program Files\Windows Sidebar\SharedGadgets as shown here.

* Wait about 30 seconds or so (to give Vista a chance to detect the added gadget) and then tap on the "+" icon (Add Gadgets button) in the toolbar at the top of Vista's Sidebar. This will display the Gadget Gallery shown below. You should see an icon for the InkPad Gadget.

* To add the InkPad gadget to you sidebar double click on the InkPad icon or drag and drop the InkPad icon to the sidebar.
The InkPad gadget should now appear in the Sidebar:

You should be able to ink in the white area of the InkPad now. To make the inkable area larger, move the cursor to the top-right edge of the InkPad (there's a five-pixel, black border around the InkPad), and a handle will appear that you can use to drag the InkPad off the Sidebar. At this point the InkPad will grow in size making it easier to jot down notes. To dock the InkPad again, reverse the process. Move the pen to the top-right, five-pixel border of the InkPad, which will display the handle that you can use to drag and drop the InkPad to the Sidebar.
As I mentioned yesterday, this is more of a proof-of-concept that a fully-functioning utility. It doesn't persist the ink or provide any user options, for instance. I'll post the source code after I get back from shopping. Maybe someone can figure out how to persist the ink or add some user options.
Let me know if this works or doesn't work on your system. It's literally a one day project so I haven't even had a chance to test it on different systems. Hopefully it runs :-). I don't know what happens, for instance, if you run the Gadget on a non-Tablet. I presume it'll work.
