Sky+HD boxes are primarily manufactured by Amstrad. Just thought i'd mention it.
Sky do have the monopoly, but their pricing is ridiculous. I've worked out what they plan to do after their price freeze ends in 2012/2013 or whenever it is. You can't add value packages for £1 each, you can only have none or all 6, meaning that the lowest you can pay is around £20, but you'll hardly have any channels or have all the value entertainment packages (music, news, educational, kids, lifestyle) and pay around £25. Then add Sky Sports (excluding ESPN) on top for £20.
As extras - unlimited broadband (£7.50/month), weekend and evening calls (landline - approx £12.50/month). so you're looking at around £70/month.
When 4G internet makes its way over here and something like Google Voice becomes popular (not the other VoIP apps - something that can actually replace your line rental), it'd save people so much on landline line rental and being forced to have a landline just so that they have home internet.
