Saving scanned document for email use

If I scan a printed document to my Mac (Snow Leopard), and save it as a PDF file, then email it to someone with a Windows PC system; they should be able to open it with Adobe Reader - shouldn't they??? Or, maybe there is an easier way! Any suggestions would be greatly appreciated.

Yes almost every computer has Adobe Acrobat Reader, so any computer should be able to view them.

Not everyone has Acrobat. You can always do a .JPG file if you are unsure!
