"The thing is, Apple is pushing the multiple-device world, and POP3 was never intended for use on multiple devices."
and
"POP never "just works" if you have more than one device. You have to set it up and use it carefully."
This would tend to support my original observation -- that being that Apple has purposely dropped POP for reasons of their own (and not for "technical" reasons). They're trying to push in a direction not of our own choosing.
In other discussion threads, there has been the back-and-forth argument that Apple's intent is to make the Mac OS "more like" the iOS -- possibly even merging the two at some point in the future. When they do things like this (i.e., "drop POP"), that lends credence to such speculation.
"Apple rarely designs with the power user in mind. It generally applies the philosophy that if you're advanced enough to want something other than the default, you'll be advanced enough to figure it out on your own."
Again, more "dumbing down" of the OS. I actually find POP much more "intuitive" than IMAP, and prefer that once I have my email "in hand", that it be OFF the server. Kind of like when your postman puts the mail into your postbox, and you pick it up. At that moment in time, your mail is no longer in the Post Office's possession, and is in _your_ sole possession. That's what I want with my email, too.
Give me back my POP!
