It would be even nicer (at least as an option) to "unfold" the whole thing to a larger rectangle... for surfing the web, video-conferencing, watching movies etc. ...

yeah i think it would be great too..

but the future is not the question here..the question here is the price..

It is not too far from being a reality. Just look at this research news from the University of Cambridge:

ive heard there are computer speakers at the size of a single page.. (for sale.. anyone can buy them)

maybe thats the new future..
probably as Sam says ; the future might not be too far away..
