Single Screen conectivity

Dear Sumant,

I been thinking about all the various electronic gazettes now merging together. You now have cellphones that multiple as still and video camera, gaming machine, mp3 player, television, internet browsing etc. However still people buy many of these things individually because of richer features when they are standalone. However thing which makes it bulky is the size of the screen and since all these devices have screen in common I think the technology companies should aim for a screen which is easy to connect to any of these devices (may be something like blue tooth technology) and can be folded and unfurled with minimum components. So all you carry is device and one screen or there will be a way to connect to any of the screen available at home like television or big LCD monitor or projectors.

Best Regards
