Another reason the keyboard should be detachable_Chrome OS

Another reason the keyboard should be detachable is because when there is an  incoming call  on the  15.6 inches  Chrome  OS   Laptop/Tablet/Smartphone   hybrid , the user can detach the keyboard from the  15.6 inches display and take the 15.6 inches  display with them and walk to another room within  and talk in private ............ eventhough the  15.6 inches Chrome OS Laptop/Tablet/Smartphone   hybrid   "keyboard"    (which is connected to a docking station) is doing something in the background , for example :

• uploading a 4 GB .iso  file or a 4 GB  video file from the Internet
•  uploading a huge file or a collection of files above 10 GB from the Internet
• printing 50-100 pages of documents to a USB printer
• watching YouTube/Videos/Movies/NetFlix/iFlix
•  transferring files from one computer to another using USB port  [ 1 2 3 4 5 ]   (work with Windows OS only)
•  transferring files from one machine to another or from one computer to another using Ethernet cable or Wireless or Bluetooth
• installation of Chrome OS application software , Chrome OS Apps from chrome web store 

Another useful feature when the  15.6 inches Display could be detached from the   15.6 inches  Chrome  Laptop/Tablet/Smartphone   hybrid    "keyboard"  (which is connected to a docking station  and doing something in the background)  is that ,  after we have completed our conversation in private or after we have finished making a call , we can use the onscreen keyboard on the  15.6 inches Display to :
1.   cancel print jobs
2.   kill pages in a printer queue , etc., etc.,
if we have problems in receiving documents from the printer .
