matthewpiano:Sky HD is NOT Full HD. Its 1080i and will remain so.
Interesting you say Full HD is not important for 1080i - I can't think of a better way of showing 1080i programmes than on a 1080p TV. Admittedly, it will need to be de-interlaced so 1080i becomes 1080p, but if you have an HD Ready TV, it will not only need to be de-interlaced, but also downscaled down to 720p. So surely, in theory, a Full HD set would be better for a 1080i signal? (NB - this is basing it on tech specs alone).
Of course, there is the argument that the majority of Sky's programmes are in SD and therefore, a Full HD set would have to do extra scaling to accommodate that on all of those programmes, so you should take this into account.
However, it's most important to note that some TVs are better than others irrespective of Full HD vs HD Ready specs and this is what people should actually be interested in.
