IF  THE  15.6 INCHES LINUX OS  LAPTOP/TABLET/SMARTPHONE   HYBRID LOOKS LIKE A LAPTOP AND IT IS DETACHABLE :

1.  the 15.6 inches Linux OS  Laptop/Tablet/Smartphone   hybrid(detachable)  must have at least 1 unit of  USB Type-C port on the  "15.6 inches  Display"  .  If the  "15.6 inches Display" is detached from the "keyboard" for some reason  , we can connect  a  USB Type-C  Docking Station to the "15.6 inches Display"  and in turn connect to various peripheral devices whenever it is needed .

2.  the 15.6 inches Linux OS  Laptop/Tablet/Smartphone   hybrid(detachable)  must have at least   3 units of full-size USB 2.0 port   or   3 units of full-size USB 3.0 port  on the  "keyboard" .
 Having 3 units of full-size USB 2.0 port  or  3 units of full-size  USB 3.0 port  in a  15.6 inches Linux OS   Laptop/Tablet/Smartphone   hybrid(detachable)  "keyboard"  is very useful .  The  first full-size USB port of the 15.6 inches  Linux OS   Laptop/Tablet/Smartphone   hybrid(detachable) on the "keyboard"  can be use to connect to a  USB scanner . The second full-size USB port of  the  15.6 inches  Linux OS   Laptop/Tablet/Smartphone  hybrid(detachable) on the  "keyboard"  can be use to connect to a flash drive or a thumb drive or 
a external hard disk drive .  The third full-size USB port  of  the 15.6 inches Linux OS   Laptop/Tablet/Smartphone   hybrid(detachable) on the  "keyboard"   can be use  to connect to a  USB Docking Station so that we can have more USB ports and connect to various peripheral devices just like a  PC .  Having  3 units of full-size  USB 2.0 port  or  3 units of full-size  USB 3.0 port is also very useful because , firstly , we can use all these 3 ports simultaneously for cloning hard disk drive and  secondly , we can use all these 3 ports simultaneously to install other operating systems (e.g.  another version of Linux OS) . 

3. the 15.6 inches Linux OS  Laptop/Tablet/Smartphone   hybrid(detachable)  must have an Ultra Slim internal DVD-RW player on the  "keyboard" [ 1 ] .
There is so much space on the left hand side and  right hand side of the  "keyboard"  on the  15.6 inches   Linux   Laptop/Tablet/Smartphone   hybrid(detachable) , 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 the   15.6 inches  Linux   Laptop/Tablet/Smartphone   hybrid(detachable)  is much more convenient/comfortable and very handy even if it makes the  15.6 inches  Linux  Laptop/Tablet/Smartphone  hybrid(detachable) , slightly thicker and slightly heavier .
  
4. the 15.6 inches Linux OS  Laptop/Tablet/Smartphone   hybrid(detachable    must have an HDMI port  on the  "keyboard"

5.  the  15.6 inches  Linux  Laptop/Tablet/Smartphone   hybrid(detachable)  must have at least  1 unit of full-size USB port on the "keyboard" and  1 unit of  USB Type-C port on the  15.6 inches  "Display"  (useful when the  15.6 inches "Display"  is detached from the Keyboard)  so that we can connect them to a  USB 2.0/3.0 Docking Station   or  a   USB Type-C  Docking Station . 
Let us say for the sake of elegance , or appearance , or 
 because the  hardware/software  manufacturer want to make
 the 15.6 inches  Linux OS   Laptop/Tablet/Smartphone
 hybrid(detachable)  thin and light and sleek and slim
 and they decided not to put so many full-size USB ports inside
the  15.6  inches Linux OS   Laptop/Tablet/Smartphone
hybrid(detachable)    "keyboard" , then the hardware/software manufacturer should put at least  1 unit of full-size USB port on the "keyboard" and  1 unit of  USB Type-C port on the  15.6 inches  "Display"  (useful when the  15.6 inches "Display"  is detached from the Keyboard)  so that we can connect them to a  USB 2.0/3.0 Docking Station   or  a   USB Type-C  Docking Station .
