It's a rubbish keyboard, and the "flat"screen CRT is way ahead

I can't find the specs or a picture online, but mid 1970's
I worked in a store that sold Sony Trinitron consumer tvs,
and they were proud of a new model that was, based on
my very shakey memory, only somewhere between one foot
and 18 inches from front to back, and with a flat screen.
Which was close enough to the displayed model that
it's certainly possible custome high-end/milspec/proof-
of-concept units might have been out there.
Their secret? The electron beam was coming up from the
bottom of the set, and was redirected 90ish degrees (depending
on how far "up" the image was) to the screen.
Warning: this is a vagueish memory as to the sizing, but
I definteily remember this line being much narrower
front to back.

The bottom half looks inspired from the teletype keyboards for the
hearing impaired you'd still find on some public phones quite recently.
To the right of the monitor is a thing that looks inspired by a
dictaphone/voice recorder.
On the other hand, let's take a moment to recognize the Future was
clearly going to involve cool mechanical keyboards. That confirms my
suspicion that the membrane and chiclet monstrosities on the market
today are a momentary aberration between the 1960s and the Future. Let
us hope.

Indeed. Also, the Q key is missing from the keyboard.

Not even close. The thinnest CRT nade was Sinclair's front view
flat CRT for the FTV1 - it was a lot smaller than the one in the prop,
possibly a little thicker and of course much later (mid 1980s). It was the
one thing Sinclair did that I think of as a real invention rather than
engineering pushed to the cost limit - it was an ingenious trick that
almost worked well.

<https://en.wikipedia.org/wiki/Rotary_dial>
I suspect using a DTMF push-button-dialpad would have looked foreign
to most all movie goers then. DTMF cost more monthly to use then, and
the local telephone exchange had to have in-place the required
equipment, which would have been phased in over a number of years
across the US.

The Osborne 1 is the first commercially successful portable computer,
released on April 3, 1981 by Osborne Computer Corporation.[1] It
weighs 24.5 lb (11.1 kg), cost US $1,795, and runs the CP/M 2.2
operating system. It is powered from a wall socket, as it has no
on-board battery, but it is still classed as a portable device since
it can be hand-carried when the keyboard is closed. ...... It is now
classified as a "luggable" computer when compared to those later
"laptop" designs such as the Epson HX-20.

Saw a MEME the other day showing a modern keyboard, but the keys ESC, CTRL
and the SPACE bar were missing. It read:

I've never forgiven them for not using the existing calculator
layout, thus perpetuating the myth that 0 follows 9 in many
people's collating sequence.
When I was 7 years old, I remember looking at the alphabet
written above the classroom blackboard, along with the numbers
1234567890, and thinking, "That's wrong. The numbers are
out of order."

I don't think you can, not with that rounded front and a single beam
anyway.

The suitcase shown in the photo doesn't give more than an inch
or two back to front. It also doesn't have space to the left or to the
bottom for the rest of a CRT tube.

The Sony Watchman CRT uses a trick like that. It's about 1" deep, but
also a much smaller and less rounded screen.
http://lampes-et-tubes.info/cr/cr037.php?l=e
The Watchman screen looks distinctly titled when you view it.

My first computer, acquired in '87 in exchange for a hand-raised
copper curry pan, when I was middle-aged and the O1 was already
obsolete. I learned Z80 assembler, BASIC, dBase II and K&R C and even
a smattering of Lisp on it. Conway's Life in Z80 assembler ran very
nicely on it on a toroidal world. In the following 6 years, I managed
to acquire seven of them, supported two other people to whom I gave
them. My wife wrote her master's thesis on an Osborne 1 in '93
(although she got it printed elsewhere). Until the early 90s, I used
it as a terminal (but not depending on the 3" screen) to log into
remote Unix and VMS accounts.
In 2005 I donated them all, along with a couple of Kaypros, to a Nova
Scotia computer museum which is itself now defunct.
My chance to catch up with things digital after a 23 year gap between
it and a short 1964 Fortran class.

I went searching for that, and googled "Lollipop CRT"
This is what came up. With only the faux wood-grain in the photo for
scale, my guess is it's something like 200mm diagonal. 100mm neck len
gth. And maybe 30mm thick.

I remember a tech at Burroughs arguing vehemently that there would
never be a market for flat screens, anything you could do with a flat
screen (according to him) you could do with a CRT. He also was dead
certain that no micro would ever be faster than Illiac IV.
The "walls" in Fahrenheit 451 are actually within the means of
middle-class wage earners today, if they don't mind lines between the
panels.

In earlier days of flat screens, their resolution sucked when compared
to CRT.
For late 1990s high dollar CRTs, it took about twenty years before
flat screens could achieve a dot pitch of 0.28 or lower.

This would have been '70s. But it was obvious even then that there
were applications that he could not envision.

In ye shedde there's been a mention of the Samsung Argentinian
(Argentine?) safety truck, that makes trucks "transparent".

(video shows erm video of the truck driver's view ahead being displayed
on 4 big LCDs on the back, so the driver behind can see if it's safe
to pass).

Bah, and indeed Humbug.

So, this Lollipop could either be a CRT, or a LCD....your cite
suggested this person was new to RCA, and worked in different
departments there.

A patent search might shed light on this topic

If you look at that thing you can tell it's a CRT. See that connector
off to the side with no coating around it? That's where the second
anode would plug in--that's typically something over 10KV and has to
be isolated from the other connectors lest it arc over to them. And
no LCD would need a neck like that anyway. Besides which why would
anybody make an LCD as a vacuum tube in the first place?
