When you receive an email message from someone with Mac Mail, the free email application that Apple installs on every Mac, you might want to save a copy of the letter as a PDF file, so you can use it on a different computer. A PDF document looks the same no matter what computer it's opened on, using an application such as Adobe's free Adobe Reader or Apple's Preview.
