I picked up an emac from the apple auction at dovebid last week and while I was gifted with the addition of a cdrw drive in what was stated as cd-rom only machine, I got one of the educational machines without a modem. what Id like to know is if theres any usb modems available that play nice with os x out of the box. I would be giving this to someone as a gift and would prefer as little complication as possible. I know airport is an option for adding dialup capability, is there anything else?
