Doing a factory reset has some advantages for a few purposes. One of the big ones is wanting to remove all Data from the device.
This is handy if you plan on giving the device to someone else and don't want to give them your contacts or any other information.
In some circumstances it can even be handy to just start over especially if you have some minor issues and you assume the issues are Data related.
If rooted its a great way to wipe the Data and Cache area's to prepare to change the ROM of the device.
