Some interesting comments here about the relative merits of Freeview v Freesat. We live in an area with relatively poor digital terrestrial reception, but with a masthead amplifier Freeview is acceptable most of the time. We can also watch Freesat via a Humax Foxsat HDR fed by a very old original Sky analogue dish (when things went digital I realigned the dish and fitted a new LNB). Freesat reception is rock solid, irrespective of weather etc., and the EPG is totally reliable, unlike the Freeview EPG which is often very slow to load. Likewise the red button feature on Freesat works fine, on Freeview it often refuses to load some pages. I also like the fact that I never have to retune the Humax - providing it is left in standby it automatically looks for any updates at 3am each morning and sorts itself out.
I agree that it doesn't make financial sense for manufacturers to include a Freesat receiver in all their TVs, but I see that J Lewis are currently selling 21 TVs that do.
