To buy or not to buy a laptop,

I've been thinking about this for a while now, my boyfriend's got a laptop for work, and he takes it home with him every night. And in makes me think maybe I should get one, a good example for when i would use it is right now, I am freezing my ass off in the living room, and if I had a laptop I would take it with me and watch a film in bed. 

But i just bought a Samsung galaxy tab 2, and I take it with me everywhere. but i cant really watch a film on it, well I guess I could, but you know what I mean? But what I really want is a TV in the bedroom i think. then I could watch a film in bed and blog at the same time. Bingo! haha. Hmm, maybe i should buy us a TV after Christmas.. or a laptop.. haha..
