That shouldn't be the trade-off, though.

I think your average smartphone owner doesn't understand all this anyway. They look at their 3-year-old phone and say "it works fine and does what I need it to do", look at the new ones on the market and say "I don't see anything compelling there to justify that price tag", and so they don't buy a new phone. Most people don't realize that their phone has gaping security holes in it that will never be addressed.
