I've had it since it came out and It's still as amazing as it was when I first got it. In fact it's better now, as it sees to be faster.

Is the speed I get so just under 7 meg.
If you've got a mobile just use it during the day (when you're probably at work anyway) - never make calls on it outside of evening & weekends - and use the house phone at night and the weekend for free (remember and hang up every 59 minutes to be sure.) It's saving me ever going over my monthly minutes on the mobile now, which used to happen a lot when I used it for all calls and never had the free calls deal!
If you only take 1 Sky mix it's only £21 a month for a few extra TV channels, "up to" 8 meg broadband with 40gb a month limit and free evening & weekend calls which you'll notice will keep your useage down on the mobile. It's £30 installation. You cannae go wrong. Some broadband providers are charging that just for the broadband!
Just be warned that Sky is frequently a pain in the arse to get installed! If it's not the need for a special heights unit there'll be a problem with the dish positioning or some cabling issues! There's always something but it always get done in the end.
