15.6 inches Linux OS Laptop/Tablet/Smartphone hybrid which have the physical appearance of a Laptop(foldable 360 degrees/detachable) or a Tablet must have an Ultra Slim internal DVD-RW player

The 15.6 inches Linux OS  Laptop/Tablet/Smartphone(ALL-in-ONE)   must have an Ultra Slim internal DVD-RW player . There is so much space on the left hand side and on the right hand side of the  15.6 inches   Linux   Laptop/Tablet/Smartphone(ALL-in-ONE), so , the hardware/software  manufacturer should include an   Ultra Slim internal DVD-RW player on this machine .  

Putting the machine on the lap and when we telecommute (bus/train/airplane/coffee shops/library) , typing documents , writing an article , doing software installation , watching DVD movies , running System Utilities Software , etc., etc., with an Ultra Slim internal DVD-RW player   inside   a   15.6 inches  Linux  Laptop/Tablet/Smartphone(All-in-ONE)   is much more  convenient/comfortable and very handy   even if it makes the  15.6 inches  Linux  Laptop/Tablet/Smartphone(ALL-in-ONE)   , slightly thicker and slightly heavier .
