i just bought a new 12 inch powerbook and i want to get air port card for wireless internet. my question is what is the best way to achieve this. i currently have a pc desktop with a cable connection, and i want to continue to use that. i just want to know what do i need beside the airport card. do i have to buy the apple base station or can i use any other wireless router to hook these two computers up? i am not very concerned with sharing files between the computers i just need to have them both connected to the internet. and maybe share a printer if its not to much trouble.
