hey guys, i need some help. i'm looking to get a wireless card for my g4 ibook that runs on tiger. i'm looking at http://store.apple.com/1-800-MY-APPL...lm=M8881LL%2FA
so far. my roommate has a wireless router so i won't need an airport (i think, is that right?) the thing is, i can't figure out if that airport card can be used in a g4 ibook.

so as you can see, i need some help. if there's a better way to go about this let me know. while im not new to macs, i am new to the wireles scene=)

thanks a ton!
