I'd love Sky HD but the offer I'm in with Virgin ties me into the phone, tinternet and telly for £90 a month, which is a bargain in the current climate.
Not forgetting that the phone has all international calls and other tit bits that we'll never use
the internet is 20Mb with a new wireless router and the telly has all the trimmings including all films, Setanta, two recording boxes and all the On Demand stuff.
The only qualms I have is that the variety of HD channels is limited at the minute, there's no Sky Sports News, Sky One, etc and the package doesn't seem to run as smoothly as the Sky+ boxes. The phone and internet is much better than the Sky ones I've used though which is a bonus.
