Let's start with why you would want to root your Android smartphone. Sometimes apps require special permission that the Android OS, which is based on Linux doesn't allow. These could be simple as taking a screenshot to higher level permissions to the core Android files. Rooting makes your phone faster, increases battery life, allows it to run more apps, custom software and ROMs which allow complete control over every aspect of your device by allowing superuser and admin level permission. Removing carrier bloatware is a particularly enticing application.
However, rooting isn't for everyone. If you don't know what a command prompt is or you have trouble handling .zip files, please don't root. The risk of bricking your expensive device to get speed gains and improvements only Android enthusiasts can appreciate is not worth it. Lastly, rooting can void your phone's warranty so please make sure you follow instructions to the letter. Also, back up your data before you root android!
