what is the benefit of jailbraking apple TV ???

hello guys , i suddenly decided to purchase an apple Tv 2 ( used or refurbished) since every apple product is jailbreakable , i can handle jailbreaking iphones , ipod, ipad  but i’ve never thought  of jailbreakaing aTV so i was wondering if someone can help me out with the Benefits of JB the aTV ?

what is the purpose of the jb ?

i know it’s about XBMC , and Nito Tv, etc … , but i really don’t know what their purpose is ?

does installing XBMC’s Plugins  give you access to free movies and sports  or what ?

thank you in advance !!!

 

Bottom line yes, but there are many other features which some are useful to some people and useless to others.
