My Sony TV has never had a software update. So are you saying that if Apple did improve their TV sets with regular updates, this would somehow be a negative?
I get the "happiness is relative" thing, and it sucks to see newer models getting extra features that yours doesn't, but do remember that your old [Apple gadget X] doesn't stop working simply because it misses out on an update.
Except it DOES stop working because of an update, there are many iOS apps i cannot install on my 3GS or iPad 1, the message, The app requires a front facing camera, how can Soul Calibur, a game that doesn't USE a front facing camera require one ?
My mother still uses her iPhone , the original one, im going to have to buy her a new one because the banking app she uses no longer works on anything less than the current iOS version.
now, on a device i get for free, or £150 subsidised by my carrier over two years, thats not to bad, i can even stomach the 4ish years support on the macbooks and iMacs as i tend to upgrade my Hardware every 5 or so years, but on a TV, costing £1500 or more i expect to get a decade + out if it
