The 3D-version of the monitor was lousy
It was supposedly somehow miraculous, remarkable and revolutionary invention - and why not, such technology would certainly be considered very advanced, considering that we still use 2D display devices, that are heavy, big and hard to lug around - it would be technically and portability-wise, an achievement for sure.
But what would be quite annoying about it, that when the guy said he didn't like the monitor, so he removed it (or something to that effect), the BACKGROUND SCENERY is also removed!
So now there's just the upper portion of some hag (that doesn't do much) on the "screen" (or whatever the space should be called), instead of having at least a monitor to frame the experience and a background to go with it.
If removing the monitor means removing everything else except one individual half-object, I think I'll stick to the actual monitor with the frame, thank you very much.
I mean, who would use such a device in practice?
You could no longer 'hide' what you are watching, from someone passing by or looking at the back of your monitor. Suddenly everyone in every direction can immediately see what you are doing. Not good if you want to do your own things at the office, or just have some privacy when others are in the vicinity (in a library, for example).
What good is a monitor that can't display a BACKGROUND?
The background is crucial in things like movies, computer and video games, and so on. You need a background to give the illusion of immersion - you need a scenery and scene to place the object or star, player or sprite in! You can't just have some torso and have nothing around it, and call it a game or a movie!
It'd be even worse than the so-called 'prequels' to Star Wars - it'd be like the actors shot against the bluescreen, except that there would not even be a bluescreen - there would be nothing, just the actors!
Can you imagine how dull (or much more dull) it would be?
Sure, achievement in many ways, but also a retardation in others.
It's like a cardboard bus ticket versus an electronic one. In many ways, the electronic one is supposedly better and higher-tech - but how easy and handy was it to see exactly how many trips you have left with the cardboard one? How easy is it to check it with the electronic one? Maybe in some countries it's possible, but in others, there's just no way for an ordinary bloke to come home and check how many trips is left in the card now!
This kind of "progression with retardation" is going on in all areas, it seems.. we got TFT monitors, which were supposedly higher-tech, sharper and higher-resolution image, without flickering, interlace, or any of those CRT effects.
But.. at the same time, you couldn't change the resolution anymore (the monitors have learned to scale a bit better nowadays, but the result, especially in lower resolutions, looks like a mixture of bat vomit and LDS-induced photoshop session). Dead pixels were introduced, that ruin your image, especially if in the wrong place, and there was nothing you could do about it. You just had to stare a white spot (or multiple ones) for the rest of the time you used the monitor, or perhaps have some black spots that remove important bits and confuse you when you are creating graphics - is that a black pixel, or .. oh, just a dead pixel). On top of that, the TFT monitors weren't nearly as bright (or luminous) as the brightest televisions and older CRT monitors (you can compare how an old VGA or SVGA game looks like on a CRT monitor and a TFT monitor bought a few years back, and see what I mean - especially if it has some kind of 'brightness' tech, like "Viewsonic UltraBrite(tm)", or if it's an old and small CRT monitor (like 13" or 14" - some of those were superbright (no tm)!)
Monitors used to have nice, round knobs that would give you instant access to adjusting anything - oh, too much contrast? Just slight sleight of hand (quick adjust from the analog knob), and you got it PERFECT, easily, intuitively and without a fuss.
Now?
You have to first uncomfortably, usually with our thumb, manage to click a tiny button, that brings up a menu (sometimes it takes a second or more to appear!), and then you just 'klik-klik-klik-klik' with your thumb, until the picture looks somewhat what you wanted it to.
How is this progress?
Anyway, I digress, but the same theme seems to go on in this movie. I must admit it's realistic, though.. because that's how the world seems to work now. Progress with retardation is the name of the game, and this movie predited that game.
