First, I apologize for causing any confusion. Definitely not my intent. Probably just a result of the state I live in... The State of Confusion!

Are you trying to tell me that I can't use my iPad to see POP email while I'm on vacation???
Not at all. You just won't be able to see any messages if you use Mail on the Mac if you download them to your iPad. Of course, you could forward them to the iCloud account and then you can see them on the Mac
and the iPad.
POP account messages are
designed to be downloaded to a
single device. Some POP servers have settings to leave a message on the mail server, but the normal method simply deletes the message as soon as you
download it. POP account are not designed to
view messages, they are designed to
download them. That is what your email app is actually doing; it is not simply displaying a message, it is downloading it.
IMAP accounts are designed to
store your messages on their servers. You can then view them in an email app on any device you might have from any location you might be, as long as you have access to he Internet. And you can do that viewing forever or until you delete the message.
If you use a good email app (like Mail), you are also making a copy of the message(s) on the IMAP account onto your device. But you still have the original on the IMAP server. That way you have the usually better, more reliable, industrial IMAP server copy, even if your local device dies, walks off, etc. A "cloud service" is, after all; a remote computer storage site that you access through the Internet. That's why I called IMAP the 'parent' of "The Cloud".
The two key differences:
POPA method of temporarily storing messages until you download them.
Designed for use with a single device.
IMAPA method that stores messages on a remote computer until you intentionally delete them.
Designed to view any message one as many devices as you own for as long as want.
Obviously, using a web browser to access the "web-based" email account (of any type) is completely independent on whether the account is POP/IMAP/gMail/Yahoo/Klingon/etc. The description above relates only to using a dedicated email application, like Apple's Mail.
