That is the question. Rooting your Android device definitely pushes you up a level or two in your geekdom. It requires a certain level of commitment, at least a little savvy, and even a modicum of risk. So, why would you want to bother?
What Is Rooting?
Rooting means gaining root access to your device. When you take your phone out of the box, while there are plenty of settings you can tweak, you can only alter what the manufacturer allows you to. By gaining root access you can modify the device's software on the very deepest level. It takes a bit of hacking (some devices more than others), it voids your warranty, and there's a small chance that you could completely break your phone forever. But you know what? It's still totally worth it for all the goodies you get access to.
