Works perfectally for me. No problems at all. BUT... you need to have a reasonably new iBook with the Radeon video chip. Go to the page here... http://www.rutemoeller.com/mp/ibook/ibook_e.html And make sure you read ALL the warnings! Also, I'd recommend trying out the "trial" code that they have: it gives you the dual screen support, but only until you reboot. So if something goes wrong, you're not stuck. Take care and be careful, --Michael.
