Wow what a friend that is......

Instead of having a mobile phone, What would happen if there is a friendly device with you that acts as all electronic devices and like a friend who can chat with you......The device is like some sort of external hard disk that easily fits in our pockets and the thing here is this device turns or changes it's shape according to the user purpose, Like am a user and i wanna make a call then i ask my device to turn into mobile so that it can make a call,or if i wanna listen some music then it turns into ipod,or i wanna play some pc games then device turns into a pc with a projector in it for display and lazer keyboard and a kind of mouse,And 
what not,other than the physical works it will help you in all kinds of mental work.......... like, If you are bored at time then you may need a friend to have chat with you but no one was near to you to have a chat then you can ask the device to wake up and act like a friend to me,then on your order the device turns or changes into a doll or some animated thing just to make involve you in the conversation and can give you the best answers as per its knowledge and your question........ it turns nearly into every electronic device as per our need.

                                                 For the first time when i had this idea, That how an electronic device which fits into your pocket may have all these abilities with extra features like changing its size and entire look according to the requirement of friendly user just on his words..........

                                                I think if device like this comes into existence there may not be a need for any extra electronic device like mobiles,laptops,watches,speakers,etc..

                                                Hope for this day to come.

What would happen if technology like this comes into existence:

Just think for a second that what would happen if there is a technology to display the things or to display the things that we generally assume in our own world of  our mega brain, in the same way as we assume it with complete cinematic effect with high visuals which may not be possible to do in the real world we live ......... For example let us assume that I want to write a book which has its own story line but due to some reasons  I may not be able to complete the book, may be some issue like I cannot frame the entire conversation between  the characters.... Which makes me disappointed with my intention which cannot be completed... Now coming to the point that I have some real issue like the one i above mentioned. So one day I thought that what would really happen with the help of these imaginary sensors that would project out the exact display of whatever I thought in my own sub conscious mind.............. Really I think this would be amazing if it is going to happen.......So that the people who are unable to convey their own feelings verbally they can use this technology to give a message.
