I agree with you by the specs and I am not trying to flame you butt as I have been told the PCMCIA bus is capable of a max throuput in the real world in/out of 2-3MB/s. This is very close to the real world throuput of the 802.11g standard. It could be that the tests of the 802.11g cards have been tested using the PCMCIA bus and therefore is being limited to that number.
All I know is that Apple went with there own interface which is very similar to a compact PCI slot because of the limitations of PCMCIA. There slot is supposed to be much faster in real world throuput. I don't have any numbers for you and we won't be able to test this theory until someone receives a new powerbook and tests it using a Airport Extreme station. It will be interesting to see how the numbers come out as compared to the pcmcia 802.11g cards.
Lastly who is using card bus? It's not in use yet is it? Maybe this is what the slot is that Apple is using. I do know of card bus and know that it has a much higher throuput then PCMCIA and you are correct is basically a mini-PCI slot.
Well, I'd like to talk to whoever you got your information from because the 16bit PCMCIA is not that slow. Perhaps what they meant to say is that 802.11g only goes that fast, which would be a much more reasonable number considering the nature of wireless communications. Card Bus is used by many things- special, high end 10/100 cards (which our lab uses), Firewire cards, anything that needs a super fast transfer rate uses Cardbus.
I do not know what interface that the 802.11g card uses because, quite frankly, I haven't seen it yet. I do know that the older airport cards were indeed just PCMCIA cards.
