I watched TV via my laptop and it freezes all the time. I can honestly say that paying out for a TV licence is not worth it. You can just use 4od and other (perhaps not so legal) sites! I barely watch my TV, i'd either doing work or going out with friends. In the first year, you're doing all sorts of things, and never find time for it. If you are thinking of getting a TV, i'd wait until you get there and see how many times you actually want to watch it. If it's a fair few, then perhaps getting a TV licence is worth it. But otherwise, i'd say there's plenty of other ways to watch stuff.
