Movie Idea - 'The Screen'

I recently submitted this idea to someone in the industry, I want to try and spread these ideas using "common channels." Ideas/thoughts/criticisms welcome.

The general idea coalesced after observing how people interact with technology (the iPad specifically) in an airport, the story of Wikileaks we're all very familiar with, the idea of a technology-driven dystopia, my attraction towards film/lit that uses the symbolism found in Plato's Allegory of the Cave (real versus illusion).

The story takes place in a dystopian future, government and business are essentially merged into a singular operating unit.  A corporation creates a device simply called The Screen, The Screen is able to externalize and display visually whatever you are thinking (everyone that wants a device gets a chip implant with an operating unit number so there is seamless interaction between the device and the mind).  Of course, this technology has some interesting results on how people interact with their environment, namely that they completely forget about the real world outside of them because they become incredibly enveloped into the realities they are creating on The Screen.  The device serves as the ultimate distraction to the real, government and corporation become more powerful, things rapidly turn for the worst.  I envision the ambiance to be very surreal, dark, gritty.  

The protagonist is just your average member of the populace who resists buying the device because of his legitimate concerns about something that makes people forget about the tangible.  The protagonist's philosophy is partially influenced by his somewhat anarchistic friend who is part of a tribal society that exists outside of technology.  His friend is a leader in a anti-technology tribal culture (but was previously working within the government as a technology consultant) that has split off from the rest of society, driven by the belief that technology has become a force to control rather than a force to connect.  The tribe sees freedom within themselves and they do not feel obligated to join what they see as the technology cult that defines the rest of society.  

After a particularly poignant tirade, the protagonist's friend goes deeper underground, he goes missing, the protagonist loses contact with him.  The protagonist has an inkling as to what he's up to.  The friend becomes a dangerous individual to the status quo, he finds out a way to disrupt the network that The Screens operate on.  The people are in disarray, their entire world-views were shaped by a device that no longer exists, they are forced to accept the reality around them which is terrible and disgusting.  The government/corporation unit searches for the perpetrator, he's branded as a terrorist, the people want this guy brought justice, executed (the Assange figure in the movie).  

However, slowly, the people begin to extract meaning from the real world instead of The Screen, and after going through the painful process of accepting the world around them, they realize that it is indeed what is real.  They realize The Screen obscured truth, rather than delivered it; however, The Screen did deliver a positive lesson to the people, that the world that exists inside their minds can be externalized, but should be done so in the "real world" which really means turning against the government/corporation that rules over them.  
The people gradually wake up and the hacker is seen as a savior figure, rather than a terrorist.  He's seen as someone who brought back awareness to the world.  As more people wake up, accept the reality around them, and learn that they should (and have the ability to) be creating a more positive reality around them rather than accepting the one that has been fed to them, the people en masse stop supporting the force-fed reality and start creating believing that the best form of resistance is through creation.  The particulars of how that work are still a bit fuzzy in my mind.  

My message is this:  I want people at the end to question progress as defined solely through technological innovation and economic growth, which unfortunately, I think accurately portrays the current value system.  I want people to think about where current trends, if extrapolated, will lead.  More practically, I want people to think about their day-to-day interactions with technology, and what the costs are.
