Get An Original Airport Card - You Won't Regret It!
is there a cheaper alternative? those apple branded cards still run quite a bit of money.
Yes, while it's possible to use the Buffalo and certain Belkin wireless cards
(which work natively with apple drivers with their Broadcom chipsets), consider this:
I put two Pismo's side by side. one with an Airport card, and the other with a Belkin
card in the Cardbuss slot. Using iStumbler's signal gauge, one Pismo was at 95%
while the other was around 10%. Can you guess which was which?
The airport card makes use of the built-in antennae which goes around the circumference
of the display lid. Last I checked, you could get an original Airport card off E-bay
for $50 - $55 (plus shipping). Get an Airport card!!
