What should I know about a tablet?

Well obviously I know enough to have bought one, and so far it suits my needs perfectly. I figured out most of the basic stuff I need to know about it. (Samsung galaxy tab 4)
But does anyone have any experience with this? Are there things I should know? Even small details, anything. This is new to me, so I probably don’t know as much as I think I do. Anything you can add would be appreciated, thank you. :)
Edit; oh and how do you copy and paste with this lol?
