I'm not taking a TV as the license fee is a bit steep considering the amount of money I'm going to have and all the other expenses (I do have a TV card but you still have to pay the fee with them). I think my accommodation is flat style with several people sharing a flat so hopefully someone in mine will bring a TV I can watch if I need to.
i can't actually get any reception in my room so if i'd bought a t.v. license before i got here i'd be really annoyed so you might want to check out what kind of reception you get first of all. we've put one in the lounge of our flat and it's good because everyone can sit around watching it and talking at the same time.
You have to take a tv so you can watch daytime television - specifically Countdown.
I didn't bring up a TV, however one of my flatmates donated his (putting it in the living room) and we bought the license between us. If you're living in a flat with a communal area than that's probably your best bet.
I tried to convince myself I wouldn't want need one beforehand, but I think I'd start to miss not having a TV.
