Stop it..

You know that's not far from what it would be like. Text will be stacked. Let me repeat that
TEXT WILL BE STACKED. Please read that, savor it, roll it around in your mouth a bit. It's not a tough concept to grasp.
Take a look at the picture below. They have fit in around 35 or so characters if you look at the text and add multiple characters for spaces, this is just a guesstimate of course. It also looks like you would easily have enough room for 3 lines of text. So using my previous example it would look like this:
Honey, can you stop and grab me
some milk? The baby just woke
up and I ran out of milk. Thanks.
Vertically I'm just guesstimating maybe what, 7 characters? So:
Honey,
can
you
stop
and
grab
me
some
milk?
The
baby
just
woke
up and
I ran
out of
milk.
Thanks.
You know what, it actually looks worse than my previous example, and I don't even think all the text would fit, it would get cut off. I understand you are going to interject some nonsense like "If I want to read my wifes text I'll just pull my phone out", but then why bother having a smartwatch? On the contrary, a horrible design decision would be to stack text vertically like that, and I mean HORRIBLE. I'm not a Samsung apologist, I am quite eclectic and use whichever company suits me. It's just in this case Samsung went with more common sense, it's not a watch that only has an hour and minute hand, it's a device that will convey information which in some cases involves lines of text.

Yes I agree 100%. It's not that I necessarily disagree with your position in certain functions, not at all. Samsung needs to have some form of rotation.
