If you do not feel 100% comfortable about rooting please please Do Not Root!
If someone doesn't feel comfortable rooting please please Do Not Encourage Rooting.
Rooting IS an incredibly easy procedure, so easy that it's harder to get it wrong and brick your phone than get it right these days... but, and it's a big but, it's massively misunderstood!
Android is based on Linux, and Linux is based on Unix. Through this heritage the administration of the system is by the root account. A root user has full access to all aspects of the device. This empowers the user to do anything they want, but it also enables the user to break the device by deleting or modifying things that shouldn't be touched.
Also any software ran by root has root privileges. Whilst su apps restrict the privileges slightly they do not fully control them, that is because rooting is not enabling su (super user, a way for normal users to gain temporary root privileges), it is changing the default login to root.
If you had a Linux computer you would not log in as root by default, and you would not give su permissions to untrustworthy users, so why would you on your phone?
Yes there are benefits to root, and someone that is proficient will have no issues, but just because it's an easy patch to apply doesn't mean everyone should apply it.
