The  [ laptop/tablet/smartphone(ALL-in-ONE) with built-in DVD-RW Player ] machine ,  which I envisioned , like for example , the  [ 15.6 inches  Touchscreen   INTEL-based  " 360 degrees foldable "   Linux  5G  Cellular Laptop with  built-in  DVD-RW  Player ]   , is not really a breakthrough invention in its own right . 

 The  [ laptop/tablet/smartphone(ALL-in-ONE) with built-in DVD-RW Player ] machine , which I envisioned ,  like for example , the  [ 15.6 inches  Touchscreen   INTEL-based  " 360 degrees foldable "   Linux  5G  Cellular Laptop with  built-in  DVD-RW  Player ] is not the work of a single person but it is a product of a long collaboration between technician , engineers , inventors , designers and many more passionate inventors and gifted designers , scattered across the worlds of scientific research and industrial design . Together they bring up a machine which we call a Laptop , together they bring up a machine which we call a Tablet and together they bring up a machine which we call a  Smartphone .  But combining a Laptop  and a Tablet and a Smartphone into one single device , into one single machine , which look something like this or this or this , I guess , no one has ever thought about it , nobody is interested !
