benifits of rooting WDTV live Gen 1 ?

[fadeous]

Hello so forgive me if i didn't put the proper version. but i bought the WDTV live when it first hit the shelf, has original firmware on it.
i know that WD quickly released an update for this, witch seemed great, but alot of people lost alot of features after the update.

after reading i have the WDTV Ethernet + Wifi

right now my WDTV
lets me plug anything in USB and works, keyboards, External drives of any size,i can access my WDTV from any PC tablet , phone, ect..
i can stream video pictures , any website back and forth. it plays all my downloaded HD bluray, 3D movies in any format either from my PC or External.
the only thing i cant do is change my theme.

so i was just curious is there any reasons to root, that would be useful ?
besides having torrent download directly from my WDTV to my Eternal

thanks !
