While that may be true for those of us nerds that always want the greatest and latest, but there are also some little old ladies that have been watching the same TV for the last 30 years and don't care about HDMI or 1080p, all they care is something that they don't have to rebuy till the day they die.
Another example is other appliances that you probably care more about reliability than new functions. Like my uncle, he has been this same rice cooker that's basically nothing more than a heater coil and a bowl on top of it for the last 30 years, all while my parents kept getting new models with fuzzy logic and all the other non-sense built in. I lost count how many times we had to replace ours.
