It takes some time to get the mapping right with the shareware software, but it works! Testing it at work since it turns out I don't have a VGA cable like I thought, cable is a DVI and sneaky apple blocked off the VGA pins to prevent the use of a cheap DVI to VGA adaptor

and Extra thanks for the Mac to VGA adaptor Little guy is like new.

DO find I still have a hard time with a tablet, it is much easier with a screen built in. My son is going to love it once I have it hooked up at home... and I ordered a cable that'll work with his iBook too.
