I'm thinking to volunteer my 12 inch Mac Powerbook G4 for an experiment in converting it to a Tablet, similarly to that done by Joseph and reported in http://www.macmod.com some time back.

I am trying to figure out what I need (besides the courage or recklessness). I think if I get one of the add-on touchscreen from http://www.magictouch.com, this should be do-able. Or maybe from Troll Touch.

Any advice on where to go for help/encouragement on this? Has anyone else pulled this off, or am I going into unchartered territory?
Thanks in advance for any advice.
