As you can see, the only major difference between the standard TrulyMail client and the portable client is that the portable client is designed to be put on some removable media (like a USB drive) and moved between computers (like home, work, Internet cafe, etc.); therefore, the portable version does not support multiple users.
The standard TrulyMail client is designed to be installed on one computer and can be used by all users of that computer. This is helpful if you have multiple people using the same computer who all want to use TrulyMail.
Do not worry, though, you can easily move your data to the other edition if your needs change in the future.
