No, the different parts of this e-mail are alternatives. Your e-mail client
picks one for you to read. Some people/clients prefer text, others html.

Yes, but it doesn't "fail". It doesn't display it, because it doesn't need to.

The general idea is that all the information is also in the HTML version.
The mail contains various forms of the same message. The client picks the most
apropriate form. You might aswell add a PDF version to the mail, and a MS
Word version, and one version using international encoding etc...
However, it's possible to not only change the form of the alternative parts,
but also change the message. This spam is an example of that. The real
message is in the HTML part, the text part only tells you that you should
look at the HTML version.

Try to explain that to a non-technical user. To them it's either supported or
not.
