For making Internet-based phone calls, it’s hard to beat Skype. If you call from one computer to another, you pay absolutely nothing—no matter how far away your recipient is.
Luckily, you can download a Mac version from www.skype.com. From there, you can audio-chat with all your Mac- and PC-using Skype buddies until you lose your voice.
Messages, Apple’s own instant-messaging program, also offers free audio chats. If you and your buddy both have Web cams or video cameras, in fact, you can make free, Internet video calls. See Chapter 13 for the details.
