For what? My answer was always for the camera! But now I have a 2-year-old phone with a pretty great camera and I'm not sure I need a slightly better one for $1000. All I need is a new battery.
But are right of course, even cameras won't save the two year upgrade cycle. There will be an even more improved camera next year, just hold out a bit longer. Repeat until the old phone is actually broken. Everybody wins (long term even phone mallets will need a livable planet)
Maybe if they come out with a phone where the battery will last for a week or more then I'll upgrade.
If someone wants a rugged, long battery life phone (this has a 6000mAh battery) it would be a reasonable bet. No different from pre-ordering from any other hardware manufacturer.
