I saw a thread on the forum before talking about drawing on tablets and Wacom pads and such, but how restrictive they were and generally expensive. I picked up the new Wacom Inkling on one of the Amazon flash sales for a hundred bucks and it may be the digital tool for those who like to draw old school - http://www.wacom.com.../mobile/inkling
Basically its a page clip/pen combination. You clip the unit to the top of a paper (I don't think it works on tabloid size paper and larger), which triggers a open document. Then you start drawing and it records everything. There is a button on the unit to tell it to create a new layer, then it closes the document when you open the clip. Connect via USB to charge and access the unit as a Flash drive and you can get your files to edit in the tool of your choice. Works pretty well for me.
