I'm sorry but this is just too stupid, and I couldn't disagree more.
Your logic is almost the exact same logic that some people use when they want to buy a big car, just because they are "way manlier" than small cars.
It's plain dumbness, and I do hope you are joking.
Anyway.. It is all about the IQ! The day when someone makes a small P&S-sized full frame body, with awesome IQ, dynamic range, clean high and low ISO, and decent AF, I will be the first photog to drop my big ass gear and go light weight! ..And I am pretty sure that many thousands will follow. At least all who mostly shoot static subjects and landscapes.
Why on earth would I want to go hiking or traveling with a bag full of bricks, if I don't have to?
