I look at rooting phones the way I look at tuning/modding daily driven cars.
When you're young and have lots and lots of free time and no real drags on your disposable income, its a lot of fun. You learn a lot about your car phone because you're always working on it (funny thing about modded cars phones, they never seem to be as reliable as stock) and you like being able to brag to your friends about all the cool stuff you've done to the car phone that makes it "better" than their car phones. Then they get in their car and drive to work in the snow and rain just like you do, only they don't have to worry about dragging the suspension over the speed bump in the parking lot, or beating a bend out of the custom wheel after hitting a pothole. Then they make a phone call, send a text, or use the stock browser and don't have to fiddle with any settings or reboot the phone twice because the radio didn't reload properly with the custom ROM.
Yeah, rooting is cool at first. You get to do a lot more stuff to your phone that you normally would. But then you wake up one day and realize you spend more time working ON your phone than you do using it, and you finally understand firsthand what your econ professor was trying to explain all those years ago about the "cost/benefit" ratio.
Today, I like my phones like I like my daily drivers. Bone stock.
