Welcome to the forums vPooch. :ciao::beer:
The easiest way to root is to use the
Nexus Root Kit. Scroll to the bottom of the post and click on the link for NZTechFreak's guide for using the root kit.
After rooting there are a lot of apps you can use that require root. For instance,
Titanium Backup for backing up apps and other useful functions,
ES File Explorer for file management,
Stickmount which allows you to hook a thumb drive or other storage with the right cable,
AdAway for getting rid of Ads. The list goes on and on.
Rooting gives you more options with your device. Like being an administrator on your PC.
The disadvantage is it voids your warranty, however, you can load the stock rom and put it back just like the day you got it. Rooting is not foolproof. You can have problems like boot loops or soft bricking, but if you just read and follow instructions it isn't difficult to root. It also seems fairly easy to fix problems using the Root Kit if something goes wrong.
I enjoy rooting because I like fiddling with things.
