Email is a fast, cheap, convenient communication medium. These days, anyone who doesn’t have an email address is considered some kind of freak. If you do have an email address or two, you’ll be happy to discover that Mac OS X includes Mail, a program that lets you get and send email messages without having to wade through a lot of spam (junk mail). Mail is a surprisingly complete program, redesigned especially for Mac OS 10.4, and it’s filled with shortcuts and surprises around every turn.
All that, and it’s free.
