It will use one of the internal PCI-Express connector of the notebook.
We do not know if Mac-dedicated drivers will be immediately available, but one could imagine that Mac OS X could natively support such card. Indeed, the 802.11n Airport chips installed by Apple in its notebook models are also connected directly to a PCI-Express port.
The target price for this card should be US$119.99.
For desktop computer, D-Link will offer a similar card based PCI-Express 1x.
It could be interesting to have a driver developed for PowerPC-based Mac as it would allow owners of the last Power Mac G5 to add 802.11n to their computer. This card has a price: US$149,99.
