We had Sky in my (4 person) shared house. Mainly because the all incusive package isn't much more expensive than Landline + Broadband costs anyway, so you might as well get the bonus of something like Sky+. We also got it half price (plus free Sky Movies and Sky Sports) for 6 months, as one of my flatmates was friends with a Sky rep. Broadband is near enough essential for Students these days - especially with more and more Universities increasingly using online resources and carrying out practically all communication via e-mail, whilst failing miserably to provide enough in the way of on-campu computer access - so, with home broadband a must, you might as well get a full package.
It's also a trivial cost when split several ways as it will be in a student house - not a significant monthly outgoing.
We used to have broadband and landline through separate suppliers and managed to save a little bit of money on our monthly bill by combining with just one provider. That was a while ago though! Still haven't given in to paid-for telly though although I have been tempted...
Have Sky but recently switched internets and BT gave us Vision on top. It is AMAZING. I was really skeptical but they preload so much. Currently watching Big Bang Theory & The Tudors from the first series.
So basically Sky for general viewing, BT for catch ups.
i have sky, used to have virgin which was a much better overall package, cheaper, better broadand (due to the signal being carried by the tv cable, not the phone cable) better catchup tv than sky, and better customer service.
unfortunately now I live out in the wilds of wales virgin is not an option!
Also, i'm a mature student with a working partner and 2 kids, so may sway the poll somwewhat!
