Interesting! http://www.vtbookdd.com/ It is a 32 MB DDR Graphics memory card (from Trident) that you can plug into your laptop PC Card slot. It allows one to connect to an external display via DVI or VGA, and allows you to span across to that moniter! It is apparently compatible with apple displays and it says it works with Apple's DVI->ADC adapter, although i'm not so sure about that. Just think tho', connecting your powerbook to TWO Cinema Displays! It supports resolutions up to 2048x1536 in 16 Million colors so it supports the 23" Cinema Displays! Another interesting product.
