But what does it do?

Poppa, why are you writing all those words for me and Mikah? Can we play a game or color pictures on it? What's this? What does that say? What if I click on those letters? Why is it purple? I want to see Spider-Man on it, no Batman; a big one. Me too, Poppa, me too, a big one, OK? No I want to do it. Me. Let me Poppa!! Nooooo!! And the inevitable :'( I would like to continue but for reasons beyond my control, we'll carry on later.
