Every self-respecting science fiction movie includes a scene with a whole wall as a display. It can be one of the walls in the kitchen, an office wall used as a computer screen, an office corridor used as part of the interior design or a building façade used as a billboard.
UPDATE, Aug 6, 2011: E•Wall part II
So walls will be displays in the future, for sure. I call it E•Wall, but I suspect Pixar will chase me for it…
Anyways, in this age of computer virtualization, where every physical computer resource can be shared with many as ‘virtual computers’, it seems silly that we should all stare into separate walls: Why not share the E•Wall in the kitchen (or living room/office) so that the whole family/group can use the same screen?
It works like this: Every member of the family/group controls the E•Wall as they see fit (oh yeah, we will fight for the E•Wall like we fit for the remote control today), so when we are alone, we can use the whole wall if we want to. But as soon as more members of the family enters the room, they can access the E•Wall through their iPhone/iPad/iPod (are you listening, Apple?), see the whole E•Wall on their screen and ‘pinch’ a portion of the wall out for themselves on their iPhone display (much like pinch works on photos today), and wirelessly transfer their iPhones content up on the E•Wall: If they are watching the news, they may not need a very large part of the E•Wall, but if an interesting video clip is on, they could enlarge the image (with a ‘pinch’) to get the details.
Other types of content could be accessed the same way: A remote (or an iPhone) can start a movie or TV-show from iTunes or any other source, and if everybody in the room wants to see it, the whole E•Wall can be used as a single display.
Or while reading the morning paper on your iPhone/iPad, you ‘throw’ a video clip up on the kitchen E•Wall, next to your children’s cartoon as they mindlessly swallow their cereals (can you tell I’m a father?).
This may be far out, but seems to me very likely to appear as soon as can be done. For all I know, Apple has this in their secret innovation chamber already, waiting for the technology to be less expensive, or so I hope…
