I have a similar problem to MDKK. I have a PB w/Airport card installed, and an iBook without. They are both currently connected to the internet via an Ethernet router. Our Appletalk printer is connected up to the network via one of those Appletalk-Ethernet converter boxes (Asanti or something).
a) How easy is it to install an Airport card into the iBook (way out of warranty), or do I have to get a dealer to do it?
b) What are the advantages of buying Airport Express - simply speed? Will both cards work with it (the PB has a 9.52 card)?
c) I presume we will be able to see and use the printer from anywhere within range of the AP transmitter?
