Do normal teenagers have Tv's and computers in there room?

first of all im 13 year old boy! -- currently I have a computer and a TV in my room so I already know what kind of trobule a computer can give you! But really should I have a computer in my room, because we already have one downstairs in the living room. and should I have a TV in my room (btw my parents can change it back at night... because there tvs hooked up 2 mine...!) we also have a TV in the living room. but its not much use to us anymore, since my parents had 2 babies so know the tvs always on treehouse or bobs and lolo DVD ! But sometimes we get 2 watch it every know and then.. ----- anyway what should I do!? best answer gets as many points as i can give! :)
