I have questions about the new Light Peak technology. I am considering buying a new PC or laptop, but would like to purchase one that can be adapted to Light Peak using an adapter card. From what I've read, the PCIe slot for an adapter card would need to support 16x speed to fully utilize Light Peak's capabilities. (This is probably more of an issue with laptops than PCs.) Is this correct? Is there anything else I should know or be asking for this purpose? Thanks to all who respond.
