The author does not seem to understand that with long upgrade cycle products, you want to include the minimal number of new / improved features. Otherwise, I won't buy a new tv for 15 years and you'll make no money. But what is that? You say you have Plasma? LED? HD resolution? Better refresh rate? Gimmicky 3D that no one supports? Of course I'll buy a new one!

With cell phones and tablets, the expected lifetime is only 1-2 years anyway.
