Re: Sky and UHD
HD was pretty much a waste of time for any sensibly sized TV. HD is a little sharper and brighter, but not so much that it's worth paying the extra for. Ever notice that the Freeview EPG relegates the HD versions of channels to the hinterlands? It's almost certain that everyone is merrily watching the SD broadcasts on their HD tellies, and they don't care.
UHD will surely be a big hit with the mugs who think their TV needs to be the size of a wall, though - I'm sure the SD Freeview signals will look great when blown up to 50 or more inches.
