i kno that the airport extreme basestation is COMPATIBLE w/ yer ibook (i have one) but it will only let you use regular airport speeds
furthermore, the airport extreme card that fits under your keyboard is NOT COMPATIBLE with your ibook, get a regualr AIRPORT CARD for your ibook.
i have an airport extreme basestation that is COMPATIBLE with my regualr airport card
get the extrme aiport station (i dont think they sell a regular aiport one anymore) and the regular aiport card for your ibook
p.s.: for an extra 50 bucks, u can get the option for expansion ports (ethernet/modem/atenna) for the extreme station for later expansion
visit apple's airport site for more
ihope i didnt confuse
