Want a tablet Mac? Got a MacBook and a Wacom tablet (They're under $100 at a lot of places)? Let's do this.
WHAT YOU WILL NEED:
Wacom tablet that's smaller than your screen (I used an 8-year-old Graphire 2 USB)
A small Philips screw driver #00
A dremel tool, or similar
Some form of MacBook case. I used one of these
Some form of screen protector - you don't want to scratch it with your stylus. I used this one
UPDATE: I chopped the cable and added this tiny hub to the lid. Now there are no loose cables, I only need a USB (A to mini B) cables to connect the tablet, and instead of losing a port, I gain three.
