Same as a rooted linux android except it's not plastered with warning messages about how you're voiding warranty, how dangerous it is, how you can't run certain software anymore, etc. Having control over your own device basically.
Edit in case I'm being too obscure: just the having of any regular linux distribution means you have a rooted device, i.e. a normal regular laptop/desktop/whatever. Or for Windows you could call it administratored or SYSTEMed or something, which is also the norm
