Before people start saying "Buy a cheap 2nd monitor", understand that I want to do this for convenience. I move my iMac between work and home on weekends. I really want to set up a 2nd monitor for my iMac for doing graphic work, photos, etc. I am wondering if it is possible to set up my MacBook as a 2nd monitor, for portability issues. I understand that buying a dedicated monitor is best, but I would really like to be able to pack up my iMac and my Macbook and be able to maintain my portability. Possible? Or pipedream? Thanks guys!
