We had one 3290 where I worked, and my guess it was an IBM promotion or
perhaps ordered by someone who found they didn't like it. So it ended
up in the tape room where it saved desk space by combining consoles for
3 LPARs with a single TSO session. I'm pretty sure it had 4 coax
cables, so in that mode the vertical split was not used.
Like Ed mentioned, I remember watching the text paint itself on the
screen as it arrived. Since the plasma only had one brightness level,
highlighted text was underlined instead. In addition, I seem to
remember the underlines appeared in a second painting scan after all the
text had already finished painting.
By coincidence, a week ago I received my monthly Model Aviation magazine
and there's a new transmitter featured that seems to have stolen the
3290 color:

The 3290 added what I think was called "DFT", or "partitioned mode" to the
3270 protocol, and allowed a smart application (afaik, ISPF is the only
application that smart) to divide up the screen into several logical
screens. The ISPF SPLITV command implemented that. Maybe some TN3270 apps
can support it, but I haven't explored it, as multiple sessions are better
anyway.
I used a 3290 for a while in the Naughty 90s, and liked it, except for the
orange display. The 3290 was a gas-plasma or something like that, so the
color was chosen by physics, not aesthetics.

Somewhere in the dim reaches of my past I think I saw mention of the
ability to split an ISPF screen vertically rather than horizontally. I've
never tried it, and I'm not sure I didn't just imagine the capability.
I used to have a 3290 "gas" panel display that had this feature.
The text was always orange, did not display high-intensity characters,
and painted very slowly. But, it was kinda cool nonetheless.
